Federal overtime law thinks in weeks. California thinks in days, weeks, and consecutive days — and the difference is real money for anyone working long or irregular shifts.
The structure, from Labor Code §510: time-and-a-half after 8 hours in a workday and after 40 hours in a workweek, plus time-and-a-half for the first 8 hours on the seventh consecutive day of a workweek. Double time after 12 hours in a day, and after 8 hours on that seventh consecutive day. A worker who pulls a single 14-hour shift is owed 8 regular + 4 overtime + 2 double-time hours — even if the week totals under 40.
The recovery statute. Labor Code §1194 gives employees a private right to recover unpaid overtime and the full legal minimum notwithstanding any agreement to work for less — plus interest, attorney’s fees, and costs. “You agreed to straight time” is not a defense; overtime rights cannot be waived by contract. For minimum-wage shortfalls, §1194.2 adds liquidated damages equal to the unpaid wages — doubling that portion of the claim.
The regular rate trap. Overtime is calculated on the “regular rate,” which includes nondiscretionary bonuses, commissions, and shift differentials — not just the base hourly figure. An employer paying time-and-a-half on base wages while ignoring a production bonus is underpaying every overtime hour. The DIR publishes the overtime rules and calculation methods in plain English.
Off-the-clock is still on the clock. Pre-shift security lines, post-shift closing duties, mandatory meetings, donning and doffing required gear, travel between job sites during the day — compensable. Timekeeping systems that auto-deduct meal periods a worker actually worked through are a recurring class-action generator for a reason.
Limitations math: three years for statutory wage claims (CCP §338), extendable to four via an unfair-competition claim under Business & Professions Code §17200. Reconstruct hours from schedules, texts, badge swipes, and your own contemporaneous notes — where the employer’s records are inadequate, the law resolves reasonable doubt in the worker’s favor.
