The headline shown here is:
“US government struggles to rehire nuclear safety staff it laid off days ago”

Did they just hand them a note saying "your fired" and escort them out of the building?
This article says:
Attempting to reach the workers, the email, which was sent to current employees, said: "Please work with your supervisors to send this information (once you get it) to people's personal contact emails."
(FYI, your != you are. use you're for this)
My understanding (from reading this and other articles on the topic) is that they blasted out mass emails to those who were fired and promptly disabled all their access and accounts (thereby preventing many of them from even getting the notice that they were fired).
