The California Supreme Court issued its long awaited ruling in Mendoza v. Nordstrom, in which it clarified California's so-called "day of rest" rule, which guarantees employees "one day's rest therefrom in seven," prohibits employers from "causing" its employees to work more than six days in seven, and exempts employees when, inter alia , the total hours of employment do not exceed 30 hours in any week or six hours in any one day.
