This is a consequential move, which will improve the lives of many working people in a number of ways. Millions of employees who work long hours will get paid overtime for the first time. Millions of other workers who have been working long hours, at a cost to their health and their families, will have their hours reduced to 40 hours a week. Millions more will get a raise above the threshold, because their employer can continue to avoid paying overtime. And hundreds of thousands of people will get jobs because employers will reduce the hours of some employees to avoid paying overtime and hire additional people to do the work at straight time wages.
