Doubling the pay threshold under which salaried workers must be eligible for overtime to $47,476 a year will make an additional 4.2 million employees, less than 3% of all workers, eligible for overtime pay. By comparison, increasing the minimum wage to $15 an hour nationally would affect about a third of the workforce. That’s not surprising, as the median wage for all workers in the U.S. in 2014 was $17.40.
