Q: I have 2.5 years of credible service with the U.S Postal Service. I will be accepting a GS/GG job very shortly. Does the time count toward vacation or retirement time? What type of documentation do I need to provide when I’m hired in three weeks?
A: Yes, it counts. And the information about your prior employment will be included in your official personnel folder (OPF), which either will be forwarded to your new agency or given to you to do that.
