Key Washington Overtime Rules & Statutory Principles
Weekly 40-Hour Rule (RCW 49.46.130)
Washington law requires non-exempt employees to receive overtime pay at 1.5 times their regular rate for all compensable hours worked in excess of 40 hours during a fixed, recurring 7-day workweek. Unlike California, Washington has no statutory daily overtime requirement after 8 hours.
Agricultural Overtime Parity (ESSB 5172)
Following the Washington Supreme Court ruling in Martinez-Cuevas v. DeRuyter Bros. Dairy and the passage of ESSB 5172, agricultural workers reached complete 40-hour overtime parity effective January 1, 2024. Overtime is owed on all farm work exceeding 40 weekly hours.
Regular Rate Components (WAC 296-128-550)
The regular rate of pay is not simply the base hourly rate. It must incorporate non-discretionary production bonuses, incentive awards, commissions, and shift differentials. Total straight-time earnings are divided by total compensable hours worked.
Blended Dual-Rate Calculations
When an employee works two or more jobs at different hourly rates within the same workweek, Washington L&I policy ES.A.8.2 requires a weighted average regular rate calculated across all compensable hours worked prior to computing the 1.5x overtime premium.
