Under the current rules, any worker making more than $455 per week or $23,660 per year is not eligible for overtime pay, a threshold that has not been significantly changed since 1975. The Economic Policy Institute estimates that if the threshold is raised to $970 per week or $50,440 per year - what the threshold would be if it had been adjusted for inflation - around 10 million workers would receive overtime pay for working more than 40 hours a week.
In addition, any workers classified as executive, administrative, or professional under the "white-collar exemption" can currently be denied overtime pay, usually time-and-a-half, if they work more than 40 hours per week. An executive title can be applied to someone even if they oversee people for only a small percentage of their job, such as fast-food shift supervisors or convenience store managers.
