The Postal Service categorizes employees into two primary groups: career and pre-career. Career employees receive a full range of benefits while pre-career employees do not yet have permanent status and do not receive full employee benefits.

As mentioned in its 10-Year Delivering For America Plan (DFA), the Postal Service began to increase the number of employees converted from pre-career to career positions. However, this increased compensation costs for the Postal Service. Our objective is to assess the financial and service-related impacts of the Postal Service's employee composition.
