Q. If you have a break in your service before you’re vested, would you still fall under your original retirement plan once you complete the five-year vesting time period?
A. If you were a FERS-covered employee, you’d still be under FERS when you were rehired. If you were covered by CSRS, CSRS Interim or CSRS Offset, you’d automatically be converted to FERS and your prior service would become FERS service.
