Q: I have 20 years of full time service. I want to stay employed and plan to go part time. Will this have a serious negative impact on me?
A: How significant it will be depends on the number of part-time hours you work and how long you do that. Go to www.opm.gov/retire/pubs/handbook/C055.pdf and scroll down to the FERS section. There you’ll find the method used to compute an annuity that includes part-time service.
