Q. How many years do you have to work for the United States Postal Service before you are pension eligible?
A. It depends on your age. CSRS and FERS employees who are 62 years old can retire with as few as five years of service or at age 60 with 20. CSRS employees can also retire at age 55 with 30 years of service; FERS employees can do that when they reach their minimum retirement age, which ranges between 55 and 57, depending on their year of birth. FERS employees have a unique opportunity to retire. They can do that at their MRA with as few as 10 years of service; however, if they do that, their annuities will be reduced by 5 percent for every year they are under age 62.
