The Associated Press reported barely a week after mass firings at the Food and Drug Administration, some probationary staffers received unexpected news over the weekend: The government wants them back.

Beginning Friday night, FDA employees overseeing food ingredients received calls and emails notifying them that their recent terminations had been “rescinded effective immediately,” according to messages viewed by AP.

In the agency’s food program, at least 10 staffers were offered their jobs back, according to a food staffer who spoke to the AP on condition of anonymity to discuss internal agency matters.

FDA staffers who were reinstated said their immediate supervisors received no explanation or advance notice on the decisions. Instead, staffers received calls or emails from the FDA’s “Office of Talent Solutions,” informing them that their access to FDA computer systems and offices had been restored.

“We are so grateful to still have you working for the FDA and serving the American public!” the emails concluded.

A week earlier, the same employees received emails stating that they were “not fit for continued employment because your ability, knowledge and skills do not fit the agency’s current needs.”
