Q. I retired in July 2011 as a FERS employee with the Federal Bureau of Prisons with more than 21 years of service. Can I work for another government agency as a GS employee full time? Will it affect my pension? A. Unless you are hired into one of those rare positions that allows you to receive both your annuity and the full salary of your new position, your salary will be reduced by the amount of your annuity.
