The Washington Minimum Wage Act (MWA) unequivocally requires employers to pay non-exempt employees overtime for all hours worked in excess of 40 hours in each workweek. Regulations issued by the Washington State Department of Labor and Industries (L&I Rest Period Regulation) are equally clear that employers must provide non-exempt employees with a paid 10-minute rest break for every four-hour period worked. Under such standards, an employer may likely believe that it has satisfied its legal obligations in circumstances where an employee misses a rest period during his or her scheduled 40-hour workweek yet is provided additional compensation for that time at his or her regular hourly rate. Not necessarily, says the Washington State Supreme Court.
