If the Trump administration reaches its goal of cutting 5% to 10% of staff, more than 100,000 people will leave the federal workforce, making it by far the largest layoff in U.S. history. The current record-holder is IBM, which cut 60,000 jobs in 1993.

Here’s what we know about the deferred resignation program offered to federal employees by the Trump administration.

A Boston federal judge temporarily blocked President Donald Trump’s resignation offer to federal civilian employees on Thursday.

By midnight today, federal workers must decide whether to accept or reject Trump’s buyout offer. What will happen to those who reject the offer and decide not to resign?

Eligible federal workers must decide by 11:59 pm ET on Thursday whether to take the Trump administration’s deferred resignation offer, which will allow them to leave their jobs but be paid through the end of September.

The scheme is part of an ongoing effort by the new administration to slash the size of the federal bureaucracy.

Unions representing many of the nation’s 2.3 million federal workers charge that the administration’s “unprecedented offer” violates the law.

Federal workers who accept the Trump administration's deferred resignation offer would work through Feb. 28 and be placed on administrative leave March 1.
