Overtime rights start with 29 U.S.C. § 207(a)(1), then shift based on state law. Example federal math: $18/hour x 48 hours = $720 regular pay (40 x $18) + $216 overtime pay (8 x $27), total $936. California Labor Code § 510 may increase this result through daily overtime and double-time triggers, while Texas generally follows federal weekly-threshold overtime without a broad daily trigger. If overtime is unpaid, potential federal remedies can include liquidated damages under 29 U.S.C. § 216(b).
