SALT LAKE CITY (AP) — Utah state employees will begin working a traditional five-day workweek after Labor Day.Gov. Gary Herbert says in a letter to employees Wednesday the four-day workweek will end Sept.6 for nearly 13,000 workers because of a bill passed by the Legislature requiring state offices to be open five days a week.Herbert vetoed the bill but legislators passed an override in May.Supporters of the bill argued managers could allow employees to work four days a week by using flexible scheduling, especially for workers who don’t interact with the public.In his letter, however, Herbert says all employees will work 8 a.m. to 5 p.m. Monday through Friday.The four-day workweek was started by former Gov. Jon Huntsman in 2008 as a way to save money.
