Q. The FERS book says you can retire at age 62 with five years of creditable service. If you worked as a regular employee, part time, 30 hours a week for five years, could you retire at age 62 with five years of part-time work; if so, would this affect your annuity payments ?
A. While your part-time work would be treated as full time when it comes to determining your years of service, your annuity would be prorated to reflect the actual time you served. The methodology is at www.opm.gov/retire/pubs/handbook/C055.pdf. Just scroll to Part 55B2.
