On Dec. 1, 2016, a Final Rule will take effect that the U.S. Department of Labor (DOL) estimates will “extend overtime protections to 4.2 million workers within the first year of its implementation.”

The rule extends overtime protections to additional workers by more than doubling the minimum salary a worker must receive to be considered exempt from overtime under the Fair Labor Standards Act (FLSA)—the federal law that governs the payment of minimum wage and overtime. The minimum salary will rise from $455 a week ($23,660 a year) to $913 a week ($47,476 a year).
