The U.S. Department of Labor has published a notice in the Federal Register proposing a new rule that could extend overtime protections to almost 5 million additional workers as early as 2016. Current law requires employers pay overtime for non-salaried workers. Salaried employees are defined by a set of criteria, including job duties and a salary threshold. The proposed new rule would more than double the salary threshold and tie it to inflation, which means more workers would qualify for overtime protections. The number of workers that would be affected by the changes varies by age, education level and state; middle-aged, educated workers would see the biggest impact.
