The Labor Department estimated that an additional 4 million lower-paid salary workers would become eligible for overtime protections in the first year under the new rule.

The overtime rule is one of the furthest-reaching economic reforms that President Joe Biden has pursued unilaterally through the federal rulemaking process. It would dramatically expand the share of workers who are entitled to time-and-a-half pay when they work more than 40 hours in a week.

A federal judge in Texas on Friday permanently blocked a Biden administration rule that would have made about 4 million more salaried U.S. workers eligible for overtime pay.
