President Donald Trump and Elon Musk have upended the federal workforce, firing top officials, grinding billion-dollar agencies to a halt and convincing tens of thousands of workers to voluntarily leave their jobs.

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

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

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

The administration set a deadline for Thursday at 11:59 p.m. Eastern for employees to decide on the offer. But a federal judge in Massachusetts paused the deadline until at least a hearing set for Monday at 2 p.

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.

U.S. District Judge George O’Toole Jr. in Boston did not express an opinion on the legality of the program. He scheduled a hearing for Monday at 2 p.m. EST.

Rattled civil servants struggled with whether to leave their posts in advance of a Thursday deadline as Elon Musk continued his push through agencies.
