Sen. Bernie Sanders (I-Vt.) on Wednesday introduced a bill to establish a standard four-day workweek in the United States without any reduction in pay.

The bill, over a four-year period, would lower the threshold required for overtime pay, from 40 hours to 32 hours. It would require overtime pay at a rate of 1.5 times a worker’s regular salary for workdays longer than 8 hours, and it would require overtime pay at double a worker’s regular salary for workdays longer than 12 hours.

The Thirty-Two Hour Workweek Act would also protect workers’ pay and benefits to ensure there’s no loss in pay, according to a press release.
