Flat-rate technicians: paid by the flag, governed by the clock

01How flat rate actually works: two clocks, one paycheck

The defining fact of a flat-rate shop is that two different clocks run at once, and only one of them pays. The flag clock measures output: every repair job carries a flag time (also called book time) — a brake job might “pay 2.0,” a water pump “3.5” — and the technician banks those hours when the job is sold and completed, no matter how long the work actually took. The wage clock is the ordinary one on the time card: when the tech punched in, when she punched out, and every minute between. Flat rate pays the flag clock. Wage-and-hour law cares about the wage clock. Almost everything on this page lives in the gap between the two.

The flag times themselves come from two sources, and the difference reaches the paycheck. Customer-pay work is flagged from commercial labor guides (Motor, Mitchell, ALLDATA) or the store’s own menu; warranty work is flagged from the manufacturer’s warranty labor schedule, and those times are almost always tighter — the factory has every incentive to pay its dealers less for the repairs it funds. A technician on a heavy warranty mix can work hard all day and still flag well under the clock. The gross for a pay period is simply the flags banked times the rate:

flagged hours × flat rate — e.g., 52.0 flagged hours × $32.00 = $1,664.00

Whether the tech beat the book or blew past it doesn’t change the pay. A skilled tech who turns a 2.0-hour job in 75 minutes “makes time”; routinely flagging more hours than are on the clock — an efficiency above 100% — is how strong technicians earn well above their hourly equivalent. The flip side is the whole legal problem: when the shop is slow, when a diagnosis won’t pay, when a comeback has to be redone for free, or when the warranty time is short, the wage clock keeps running while the flag clock sits idle. Those are real, controlled, on-premises working hours that produce no flags — and they are exactly the hours the law asks about.

• Flag rate: the tech’s pay per flagged hour, typically tiered by certification (lube/C-tech up through A-tech and master), often with manufacturer-certification bumps.
• Effective labor rate (ELR) and the shop’s door rate are the dealer’s economics, not the tech’s — but they explain why dispatch decisions (who gets the “gravy” jobs versus the diagnostic dogs and warranty crumbs) move paychecks as much as skill does.
• Guarantees: many stores promise a floor — a minimum per day or per period — against flags. Whether that floor is a true guarantee or a recoverable draw is, as the rest of this page shows, very nearly the whole legal ballgame.

Keep the payroll ledgers separate

That separation matters most when a plan uses a production-bonus formula — target earnings from assigned units produced, minus the all-hours base already paid. The surplus can be made contingent on a closed RO, a comeback rule, or a specific payer reversal if the written plan says so. But statutory lines do not wait for an RO to close: rest/recovery pay, training pay, nonproductive time, overtime, and the all-hours base are wages for time already controlled by the employer. A clause that says multiple “pay elements” are unearned until a closed RO has to be read around those statutory lines, not through them.

Run adjustments in the right order

When a warranty audit, comeback, split-allocation, or payer reversal arrives after payroll, the adjustment should move through the ledgers in order. First identify the RO and the plan term that made the production bonus unearned or adjustable. Then recalculate only the bonus or unit-credit line. If a lawful adjustment changes nondiscretionary remuneration for a workweek, check whether the overtime or premium-rate math also needs a correction. Stop before any reduction reaches the all-hours base, training, rest/recovery, NPT, overtime, vested vacation, or final-pay lines. The same discipline applies to upward corrections: if an RO adjustment increases units produced or production bonus, the wage statement should show the positive true-up rather than burying it in a later net. That order is what keeps a bonus adjustment from becoming a wage-floor deduction.

02What flat rate is, legally: piece-rate, not commission

Putting the right label on flat-rate pay is not academic — the label decides which rules attach. Courts and enforcement agencies overwhelmingly treat flat rate as piece-rate compensation: payment per unit of output, where the unit happens to be a flagged hour rather than a bushel picked or a garment sewn. California’s courts said it squarely in Gonzalez v. Downtown LA Motors (2013), and the California Labor Commissioner has taken the same view for decades. The consequence is immediate: a piece-rate worker in California is owed everything in Labor Code § 226.2 — separately paid rest periods, separately paid nonproductive time, and itemized statements for both — layered on top of minimum wage and overtime.

What flat rate is not, at least in California, is a commission. That distinction is the hinge that sends two people on the same service drive to opposite legal answers. Under Keyes Motors, Inc. v. DLSE (1987) — itself a dealership case — pay is a commission only when it is (1) measured as a percentage of the price of a product or service, and (2) earned by an employee principally engaged in selling that product or service. A technician satisfies neither prong: she is paid by the flagged hour (a unit of time-valued work, not a percentage of price), and she produces the repair rather than selling it. The court put the point in plain shop language — that “[c]ommon sense militates against conceiving of auto mechanics as ‘commission salesmen’ any more than plumbers or electricians simply because their employers sell automobiles.” A service advisor, who writes and sells the repair order on a percentage of labor gross, can satisfy both — which is why the advisor may use California’s commissioned-employee overtime exemption and the technician never can.

Why a dealer ever reaches for the commission label is no mystery: in California it is the one overtime exemption shaped to fit how output-paid dealership money flows, so if flag pay could be called a commission, the daily-overtime problem would vanish. It cannot. The two readings sit side by side:

03The federal rules: overtime-exempt, never floor-exempt US

For a technician at a franchised or used-car dealership, § 13(b)(10)(A) means no federal overtime entitlement, ever — not at 45 hours, not at 60. But the exemption is surgically narrow: it lifts the overtime premium and nothing else. Minimum wage, recordkeeping, and child-labor rules remain in full force. Three boundaries are where the cases are actually fought:

• The establishment must primarily sell vehicles. An independent repair shop, a quick-lube chain, a tire store, or a body shop is not “primarily engaged in selling vehicles,” so its mechanics keep federal overtime on identical flat-rate plans — unless a separate § 7(i) retail-commission exemption applies, which in some circuits can reach flat-rate service pay. Flat-rate overtime cases at independent shops are a steady federal docket precisely because the same pay plan is exempt across the street and not exempt here.
• “Mechanic” means mechanical work. The Department of Labor’s regulation (29 C.F.R. § 779.372) reads the term functionally: a mechanic is an employee primarily doing mechanical work in the servicing of a vehicle. The reg then names what does not count — and the list is closed and specific. The exemption does not reach an employee primarily engaged in “washing, cleaning, painting, polishing, tire changing, installing seat covers, dispatching, lubricating, or other nonmechanical work.” So express-lube techs, detailers, tire-busters, get-ready and lot staff, and the dispatcher usually fall outside the exemption, and body-shop paint work is excluded by name. The badge on the uniform is irrelevant — the test is what the employee primarily does.
• “Primarily engaged” is a majority-of-time test. The same regulation reads “primarily” as over half the employee’s time. A “tech” who spends most of the week driving parts, shuttling customers, or writing service has a genuine argument that the exemption fails and federal overtime is owed.

On the minimum-wage side, § 13(b)(10) does no work at all, and federal compliance is measured the forgiving way — by workweek averaging: total pay ÷ total hours worked must clear the federal minimum ($7.25). Even that lenient test has two traps that recur in flat-rate shops. The first is the genuinely dead week — heavy clock hours, few flags, a divisor that drags the average under the floor (the slow-week example in § 07 works the arithmetic). The second is tool cost. Under 29 C.F.R. § 531.35, wages must be paid “free and clear”: the cost of tools of the trade that primarily benefit the employer is treated as a “kickback,” unlawful in any workweek in which it cuts into the minimum wage or the overtime due. The broader sweep — “other materials and services incidental to carrying on the employer’s business” — lives in the cross-referenced § 531.32(c); § 531.35 itself is the free-and-clear command. California goes considerably further on both fronts, which is where the rest of this page lives.

04The floor under every hour: Armenta, Oman, and the no-borrowing rule CA

California does not average. Where federal law lets a flat-rate shop divide a week’s total pay by its total hours and call it a day, California asks a stricter question of every single hour. The rule comes from Armenta v. Osmose, Inc. (2005): minimum wage attaches hour by hour, and an employer may not borrow compensation owed for productive hours to paper over hours that were paid nothing — “regardless of whether the average of paid and unpaid time exceeds the minimum wage.” A tech can flag $42 an hour across the week and still be underpaid if a single clock hour went uncompensated, because the high-flag hours were pay for that work, not a slush fund for the waiting.

The California Supreme Court refined — and reaffirmed — that principle in Oman v. Delta Air Lines, Inc. (2020). Oman restated the anti-borrowing core of Armenta in so many words, but it located the operative question in attribution: what does the pay formula actually promise, and for which time? A formula that pays some tasks generously while assigning zero to other compensable time is borrowing, and unlawful. A formula that, by its own design, guarantees at least the minimum wage for all hours worked — as the Court found Delta’s formula did, because its pay calculations resolved to an hourly figure above the minimum — complies, even though it is not a literal per-hour wage. The lesson for a service department is precise, and easy to overstate in the wrong direction: Oman is not a rule that every hour must carry its own separately stated wage, and it did not abolish formula pay. It is a rule against borrowing — against letting pay earned for one slice of time stand in for pay never provided for another.

The heart of Oman for a flat-rate shop is how it distinguished — and pointedly did not overrule — Gonzalez. The difference is what the formula promises, and the mechanism is worth walking through:

1. Promise by the task → borrowing (the Gonzalez facts)

   A flat-rate plan promises pay per flag hour for repair tasks. That promise attaches the money to the repairs. When the tech is clocked in but waiting — no repair, no flag — the plan has promised that time nothing. Covering the wait out of the flag earnings is borrowing pay promised for the repairs to fund time the plan left unpaid. Unlawful.

2. Promise by the unit, with a floor under every hour → no borrowing (the Oman / Delta result)

   Delta’s formula promised pay “by the rotation,” and every rotation, run through the formula, always resolved to more than the minimum wage for every hour worked. There were no guaranteed-rate hours sitting unpaid from which anything could be borrowed — the formula itself guaranteed each hour cleared the floor. Lawful.

3. The test that falls out

   A non-hourly formula complies if, for each compensated unit, the promised pay is at least the minimum wage for every hour worked, with no hour left for the formula to borrow against. Oman added that the Legislature “endorsed Gonzalez’s overarching principles and codified” a separate-pay right in Labor Code § 226.2 — the enactment that, by its own legislative analysis, “codifies the Gonzalez and Bluford decisions” — so the no-borrowing rule is now both decisional and statutory.

Two dealership-shaped cases mark the poles, and between them sits every flat-rate plan in the state:

Gonzalez v. Downtown LA Motors (2013) is the violation pole made concrete. A class of dealership technicians (about 108 of them, on the widely reported figure) earned a flag rate that beat minimum wage handily on flagged work — but nothing for the hours spent clocked in and waiting between repair orders. The Court of Appeal held the store owed separate hourly pay for that waiting time, because the flag earnings paid for repairs, not for the wait; the high average could not be borrowed to cover the gap. The judgment, with penalties, ran to roughly $1.5 million — for waiting time alone. The companion rule comes from Bluford v. Safeway Stores (2013): under piece-rate, a rest period is separate nonproductive time that must be separately compensated, never folded into the piece rate — the principle § 226.2 later codified.

The compliance pole now has a concrete, published example. In Mora v. C.E. Enterprises, Inc. (Cal. Ct. App., 2d Dist., certified for publication Nov. 18, 2025), a dealership paid its service technicians 2× the minimum wage for every hour on the biometric clock — waiting and nonproductive time included — and paid a flag bonus on top. The court held that plan did not violate the Gonzalez no-borrowing rule or § 226.2: because every clocked hour drew the same at-least-2×-minimum rate and the flag bonus was additional rather than a substitute for hourly wages, there were no underpaid hours to borrow against. The right way to read Mora is narrow and exact — “all hours paid hourly, with a bonus on top, avoids borrowing,” not “flat rate is blessed.” It is today’s clearest published statement of the compliance pole, and it satisfies Oman head-on: when no hour is ever unpaid, there is nothing to borrow. The guaranteed-hourly designs in § 10 are built to land exactly here.

05The California stack CA

California has no § 13(b)(10) analogue, so a flat-rate technician is fully non-exempt, and the no-borrowing floor from § 04 is only the first of several obligations that stack on top of the flag rate. None of them is satisfied by paying flags, however generous the flag rate.

Overtime — by the day, not just the week

Under Labor Code § 510 and Wage Order 7, a non-exempt technician earns 1.5× after 8 hours in a day or 40 in a week, and 2× (double time) after 12 in a day — plus 1.5× for the first eight hours of a seventh consecutive workday and 2× beyond that. Because flat rate is piece-rate, the regular rate that prices those premium hours is total workweek earnings ÷ total hours, and only the extra half-time (or, for double time, an extra full-time) is owed on each overtime hour, since the flags already paid straight time for every hour. A monthly spiff or production bonus left out of that computation quietly shorts every overtime hour it should have lifted — the arithmetic is worked step by step in the regular-rate engine. And a tech who turns big flag numbers on a single Saturday can hit daily overtime, even double time, without ever crossing 40 for the week — exposure a federal, 40-hour mental model never sees.

Labor Code § 226.2 — the piece-rate surcharge

Effective January 1, 2016 (added by AB 1513), § 226.2 requires piece-rate employers to pay for two kinds of time the flag rate ignores, each as its own separately stated line:

1. Rest and recovery periods — at the average hourly rate

   The statutory rate is the higher of minimum wage or an average hourly rate: the workweek’s total compensation (excluding rest-period pay and the overtime premium) ÷ the workweek’s hours (excluding rest periods). A flat-rate tech’s ten-minute breaks are therefore paid at her earned average — often $35–$45/hour — not at minimum wage. Folding the break “into the flag rate” is precisely what the statute forbids.

2. Other nonproductive time (NPT) — at no less than minimum wage

   NPT is time under the employer’s control that is not directly related to the piece-rate activity and is not a rest period: waiting on dispatch, shop meetings, manufacturer training, cleanup, shuttle runs, comebacks. It must be tracked and paid at the applicable minimum wage or higher — and “applicable” means the highest of the federal, state, and any local minimum, so a tech in a city with its own ordinance is measured against that higher number.

3. Itemization — both lines, on every statement

   The wage statement must separately show the total hours, the rate, and the gross paid for rest-and-recovery periods, and again for NPT. A stub reading only “FLAG HRS 52.0” is itself a violation, carrying its own wage-statement penalties.

(AB 1513 also opened a one-time affirmative defense — a “safe harbor” for employers who paid specified back wages for the 2012–2015 period by a December 2016 deadline. That window has closed; the safe harbor is history now, not a live option for a current plan.)

06One understated rate, three underpaid checks: Ferra CA

Everything above produces a single computed number — the regular rate, total workweek earnings ÷ total hours — and that number is not consumed by overtime alone. The same figure prices California’s missed-break premiums. Ferra v. Loews Hollywood Hotel (2021) holds that the meal- and rest-period premium owed under Labor Code § 226.7 is paid at the “regular rate of compensation,” and that this phrase means the same overtime regular rate — flags, spiffs, and nondiscretionary bonuses folded in — not the bare hourly base and not the minimum wage. For a flat-rate tech, that one shared input means a single mistake propagates:

1. Overtime is shorted

   Every daily and weekly overtime hour is priced off the regular rate. Leave a monthly spiff or production bonus out of the computation and the rate is too low, so each premium hour pays too little. The mechanics are worked line by line in the regular-rate engine.

2. Every meal and rest premium is shorted

   Under Ferra, a missed-break premium is one hour at the regular rate. The Marisol week in § 07 carries a regular rate of $39.96 — so a missed meal there owes $39.96, not minimum wage and not a stripped-down base. Pay premiums at the base and every one is underpaid by the same gap that underpays overtime. See rest-period & NPT pay.

3. The wage statement goes inaccurate

   Once overtime or premiums are understated, the itemized statement (§ 226) is wrong as a matter of arithmetic — a derivative defect. It is not strictly automatic, though: the § 226(e) penalty still requires a knowing and intentional failure, so a documented, good-faith computation can defeat the penalty even where the math was off.

This is why a rate error is never one violation. It is a common cause — one uniform formula, applied to every tech on the plan, corrupting overtime, premiums, and the statement at once. The wrong is structural and classwide, which is precisely what makes it a class action rather than a scattering of individual disputes.

07Worked weeks, end to end CA US

Two paychecks make the rules concrete. The first is a California dealership tech, where the full § 226.2 stack applies; the second is a tech at an independent shop with no § 13(b)(10) exemption, where federal law alone governs — a useful contrast, because it shows that even the forgiving federal regime has teeth. Watch, in the first, how the lawful total decomposes, and note that the difference between it and a “flags only” check is exactly the borrowed slice from § 04: pay earned on the wage clock but never cut.

Now the same trade at an independent repair shop — no franchise, not “primarily engaged in selling vehicles,” so § 13(b)(10) never applies and federal law governs in full. There is no § 226.2 stack here, but the two federal traps from § 03 are live: workweek-averaging in a dead week, and § 778.111 half-time overtime in a busy one. Take a tech flagged at $30.00, two different weeks:

08Tools, boxes, and uniforms CA US

Technicians own more equipment than any other hourly trade in the building — a rolling box and a tool inventory that routinely runs into tens of thousands of dollars. Who must pay for the tools, and what happens when their cost touches the wage floor, is its own body of law, and it stacks three rules on top of one another.

1. CA Wage Order 7 § 9(B) — the 2× hand-tool line

   Where tools or equipment are required by the employer or necessary to the job, the employer must provide and maintain them — except that an employee earning at least 2× the state minimum wage may be required to provide and maintain hand tools and equipment customarily required by the trade. In 2026 that line is $33.80/hour. Below it, the store furnishes the tools; at or above it, a tech can be made to bring the customary hand tools — but not the shop’s specialty diagnostic equipment, scan tools, lifts, or machines, which stay the employer’s to provide. (Section 9(A) of the same order governs uniforms; the tool rule is 9(B).)

2. US 29 C.F.R. § 531.35 — free and clear

   Federally, wages must be paid “free and clear.” A required tool purchase that primarily benefits the employer is a “kickback,” and it is unlawful in any workweek in which its cost cuts into the minimum wage or the overtime owed. The federal rule has no 2× safe line — it is a floor test, workweek by workweek — so it can bite even where a tech earns well above minimum, in the specific week a large mandatory purchase lands.

3. CA Labor Code § 2802 — necessary-expenditure reimbursement

   Independent of the wage floor, California requires an employer to reimburse all necessary expenditures an employee incurs in discharging duties. For tools the store could have required a sub-2× tech to buy, or equipment that benefits the employer, § 2802 supplies a separate reimbursement obligation that does not turn on whether the floor was breached. It is a different question from the wage-floor analysis, and it can be owed even when minimum wage was satisfied.

The practical line for a flat-rate shop: a tech buying his own $40,000 box on a tool-truck note is ordinary and lawful; trouble starts when a purchase is required, benefits the shop, and either drags effective pay below the floor in the week it hits or goes unreimbursed under § 2802 — and when a tech paid under $33.80 is made to supply tools the employer was supposed to provide. The full treatment, including uniforms and the laundering question, is in tools & expenses.

09Where flat-rate plans break

Almost every flat-rate claim is a variation on a single theme — the wage clock ran and the flag clock did not, and nobody paid the difference. The recurring failure modes:

• Unpaid gap time. Techs clocked in, waiting on dispatch, paid nothing for the wait. This is high-risk and directly contrary to Gonzalez in California; even at a federal-only shop it threatens minimum-wage averaging in a slow week. This is the single largest source of dealership technician class actions.
• Unpaid training. Manufacturer certification modules — increasingly done at home, after hours — are compensable work time, and they are usually flagged at zero. Recurring EV and ADAS recertification makes this a growing line of exposure. See off-the-clock work.
• Rest breaks “included in the flag rate.” California rejects the argument categorically: § 226.2 demands a separate rest-and-recovery line at the average rate, and a break that produces no flags but is “covered” by the flag rate is borrowing by another name.
• Guarantee games. A “draw against flags” that is clawed back from later checks can convert already-paid hours into unpaid ones retroactively, and can drive a thin week below the floor. A lawful guarantee is a true floor the tech keeps, not a loan against future production. See chargebacks & draws.
• Overtime never computed. At independent shops (no § 13(b)(10)) flat-rate pay with no overtime line is the most common FLSA violation in the trade; in California, overtime is owed at every dealership, and a spiff left out of the regular rate shorts it further.
• Premiums paid at the wrong rate. A missed-meal or missed-rest premium paid at minimum wage or a bare base instead of the Ferra regular rate (§ 06) — the same understated-rate error as overtime, on a second pay stream.
• Comebacks and warranty redos for free. A repair that fails and must be redone often pays the tech no second flag, but the redo is controlled, on-premises work time — compensable NPT in California, and clock time that drags the federal average in an independent shop.
• Production-bonus chargebacks that reach wage-floor pay. A store can define when a production bonus is earned and can reverse an unearned bonus tied to a specific RO, but the reversal cannot invade the all-hours base, training pay, rest/recovery pay, overtime, or final wages that have already vested. Unit credits and assigned unit values should be dated and knowable; “sole discretion” applied after the work is done is a weak substitute for a record the tech can reconcile.
• Unit-production discretion with no audit trail. Assigned unit values, labor-guide sources, split allocations, comeback flags, and warranty reductions can change a production bonus dramatically. If those inputs are personal, discretionary, or source-dependent, they need a dated record before payroll reconciliation; otherwise the “bonus” begins to resemble a post hoc wage trim.
• Tool costs. A tech buying his own $40,000 box on a tool-truck note is ordinary; required purchases that drag pay below the floor are not — and in California the employer must furnish the hand tools unless the tech earns at least double the minimum wage ($33.80 in 2026), with § 2802 reimbursement layered on top (§ 08).
• Wage statements that hide the ball. No rest-period line, no NPT line, no piece-rate units — each defective statement is its own violation in California, with penalties that stack independent of the underpayment itself.

10Compliant designs that keep the incentive

Flat rate is not doomed — it just has to be built on a time-based chassis, so the wage clock is always satisfied before output pay is layered on. Three designs do that, each landing on the compliance pole from § 04:

• Piece-rate plus the § 226.2 lines (California): keep the flags, add separately paid rest periods at the average rate and NPT at an hourly rate, and itemize all of it. This is the California worked week in § 07 — flag pay intact, with the floors paid on top.
• All-hours hourly with a flag bonus on top: pay every clock hour at one hourly rate at or above the floor, and pay flags as an additional bonus, never as a substitute for the hourly wage. Because every hour is already paid on its own, there is nothing to borrow — the design satisfies Oman’s attribution test and Labor Code §§ 1194/1197 directly. This is exactly the plan upheld in Mora v. C.E. Enterprises (2025), where the store paid 2× minimum for all clocked hours (the tech-tools rate from § 08) and layered the flag bonus above it. It is the current published example of getting this right.
• Guaranteed-variable-hourly: a variant where the hourly rate itself rises with production rather than a separate bonus line — still every clock hour paid, the incentive living in the rate. Sound for the same reason: no unpaid hour, nothing to borrow. (This is the architecture litigated in the Certified Tire cases; rely on the rule, not on those opinions — see the status note.)
• Hourly base plus production bonus: the simplest to administer; just remember the bonus is nondiscretionary remuneration that must flow into the overtime regular rate (§ 06; see Alvarado in the case library). A unit-value formula — for example, target earnings based on assigned units produced, minus the base already paid — can work only if the base, training, rest/recovery, overtime, and final-pay lines are true wages the tech keeps, not loans later recaptured by production adjustments. “No pro rata bonus for partial periods” is safest when it applies only to the extra production bonus; it cannot erase hourly, training, rest, NPT, overtime, or other wages already earned during the partial period.

11Proving it: the records a plan lives or dies on

A compliant design is only half the job; the other half is proof. Mora (2025) is as much an evidence lesson as a pay-design lesson — the technicians’ PAGA claims failed for an inadequate evidentiary record, while the dealer’s defense held because its timecards, flag sheets, and pay stubs actually reconciled to a legal theory. Either side litigating a flat-rate plan is really litigating a stack of documents. The checklist a careful shop keeps — and a plaintiff’s expert demands in discovery:

1. Timecards capturing all clock hours

   Punches that record every minute under the employer’s control — including waiting, meetings, training, and shuttle runs — not just the hours that produced flags. Gaps between “clocked in” and “flagged” are where the case is won or lost.

2. Flag sheets tied to the timecards

   The flagged hours per job, reconcilable against the same period’s punches, so the productive and nonproductive slices of each day can be separated rather than assumed.

3. Pay statements with the § 226.2 lines

   Separate, itemized rest-and-recovery and NPT lines — hours, rate, and gross for each — alongside the flag units, so the stub itself shows the floors were paid (and is not a standalone § 226 violation).

4. The thresholds, dated

   The tool rate (≥ $33.80 in 2026 if techs supply hand tools), the rest rate computed at the week’s average, and the local minimum wage actually in force at the shop’s location — each pinned to the period it governs, because all of them move on a calendar.

5. Production-bonus inputs and adjustments

   The assigned unit value, units produced, labor-guide source, RO close date, comeback flag, split-personnel allocation, warranty or factory adjustment, and any chargeback reason code. Those records prove that a bonus adjustment stayed in the production-bonus ledger and did not raid the base, training, rest/recovery, overtime, NPT, or final-pay ledgers.

6. A reconciled sample week

   One worked week, run end to end like § 07, showing flags + NPT + rest + overtime ≥ every applicable floor for every hour. If a single representative week reconciles cleanly, the plan can be defended; if it cannot, no amount of design language will save it.
