Most USPS postal employees are paid under the Postal Field Service Compensation Act. Salaries are established for different job grade levels, which depend upon each position's responsibilities and the amount of knowledge, experience, and skills required.
United States Postal Service clerks earned median annual salaries of $48,330 in May 2019, according to the U.S. Department of Labor. Ten percent earned $36,990 or less, while the top 10 percent earned $64,420 or more annually.
Fringe benefits for USPS postal clerks and substitute workers are generally the same as for all postal employees. Benefits include 13 days of annual vacation for each of the first three years of service and 20 days each year thereafter until 15 years of service are completed. Thereafter, postal clerks receive 26 days annually. Additional benefits include retirement benefits, disability benefits, health and life insurance, and paid sick leave.
