The Trump administration offered two million federal workers eight months of pay in exchange for their resignation, sparking confusion about what the buyouts mean for workers and whether they’re even legal.

Federal employees who accept the buyout would be given 8 months of pay and benefits through September and are exempt from return-to-office policy.

Federal workers who don’t want to return to the office are being offered buyouts, according to a memo posted to the US Office of Personnel Management’s website Tuesday night.
