Most specialty subs think of timecards as a payroll input. In California, the timecard is a legal record in the most-litigated wage-and-hour jurisdiction in the country — and the rules differ from the federal ones your out-of-state peers know. Daily overtime, mandatory meal and rest periods, and premium pay all get proven (or lost) on what your foremen write down at the end of each shift.

The short version

  • California overtime runs by the day: time-and-a-half after 8 hours, double time after 12, plus seventh-consecutive-day rules — not just the federal 40-hour week.
  • A 30-minute meal period must start before the end of the fifth hour of work, with a second before the end of the tenth. Missed, short, late, or interrupted = one hour of premium pay per day.
  • Rest breaks are paid: 10 minutes per four hours (or major fraction) worked.
  • Timecards should capture actual start, stop, and meal-period times to the minute — rounding policies have become indefensible in California.
  • Violations multiply per worker, per pay period — that’s how a sloppy timecard habit becomes a six- or seven-figure claim. Union subs under a qualifying CBA may sit outside parts of this regime; know which rules your agreement actually displaces.

Overtime: the day matters, not just the week

For non-exempt construction workers, California requires time-and-a-half after 8 hours in a workday and after 40 in a workweek, and for the first 8 hours on the seventh consecutive day of a workweek. Double time kicks in after 12 hours in a day and after 8 on that seventh day. The practical trap: a crew that works four 10s is owed daily overtime every one of those days under the default rules — unless a valid alternative workweek schedule was adopted by formal election before the fact, or a collective bargaining agreement with its own overtime terms applies. “The crew prefers four 10s” is not a defense; the paperwork or the CBA is.

Prevailing-wage jobs stack on top of this: public-works determinations carry their own overtime, Saturday, Sunday, and holiday rates by craft. The timecard has to know which day of the week and which classification each hour belongs to, because the rate does.

Meal and rest periods: the most expensive 30 minutes in construction

The meal-period rule is precise and unforgiving: an unpaid, uninterrupted, duty-free 30-minute meal period that begins before the end of the fifth hour of work. Crew starts at 6:00, lunch must start by 11:00 — 11:10 is a violation even if the break was a full half hour. A second meal period is due before the end of the tenth hour on long days. Waivers exist (shifts of six hours or less; the second meal on shifts up to twelve, if the first was taken) but they’re narrow and should be written.

Rest periods are separate: a paid 10-minute break per four hours worked or major fraction, as practicable in the middle of each work period. Rolling the rest breaks into lunch, or “working through break to leave early,” doesn’t satisfy the rule.

Each type of violation costs one hour of premium pay per worker per day, and the premium is owed at the worker’s regular rate of compensation — including nondiscretionary extras, not just base wage. On a 20-person crew with a systemic 15-minutes-late lunch habit, that’s 20 premium hours a day, every day, accruing silently until someone files.

Why this becomes a seven-figure problem

Wage claims in California multiply along three axes: per worker × per pay period × per violation type, with waiting-time penalties, inaccurate-wage-statement penalties, and attorney’s fees stacking on top. Representative actions let one former employee assert the pattern on behalf of the whole crew, going back years. The defense that wins these cases isn’t a good lawyer — it’s boring, complete, contemporaneous time records showing compliant practices. One nuance worth knowing if you’re signatory: California carved qualifying construction-industry CBAs out of parts of the private-attorney-general regime, and CBAs can lawfully vary several Wage Order rules — but the carve-outs have conditions, and “we’re union so none of this applies” overstates it badly. Have someone verify which rules your agreement actually displaces.

What the timecard flow has to capture

  • Actual clock times, to the minute — start, meal out, meal in, stop. Not “8 hours,” not quarter-hour rounding. California courts have grown openly hostile to rounding, and meal-period timing cannot be proven with rounded punches: the record has to show the meal started at 10:58, not “about 11.”
  • The meal period as an affirmative record, not an assumption. A missing meal punch reads as a missed meal. Some crews auto-deduct 30 minutes — in California that’s a liability generator, because it papers over the days the break didn’t happen.
  • Classification and work type per block of hours — this drives overtime rates, prevailing wage rates, and certified payroll all at once.
  • The worker’s own attestation, daily or weekly: hours correct, meal periods provided. Not bulletproof, but a contemporaneous signature beats a five-year-old memory in every hearing.
  • An exception path — when a break genuinely couldn’t happen, record it, pay the premium that pay period, and note why. Paying premiums as they occur is dramatically cheaper than paying them discovered-all-at-once, with penalties, in litigation.

The theme across all of it: in a dispute, the absence of a record is treated as your problem, not the worker’s. Foremen who close out every shift with real times, real breaks, and a signature aren’t doing payroll admin — they’re building the only defense that works.
