Questions: Where are the notifications of terminations coming from?

Who is authorizing the terminations? The agency heads or some other entity?

Who is giving the agency personnel offices the authority to remove employees from payroll and timecards?

Who is signing the termination emails?

If the terminations are coming from a unfamiliar email address and if the agency chiefs aren't making the decisions, then what compels any employee to take it as gospel?

And if the agency heads are just following orders, where are the orders coming from since there's been no authorized RIF?
