The Unites States Postal Service (USPS) offers a savings bond program for its employees. Working with the U.S. Department of Treasury and the Savings Bond Program, the USPS allows employees to use a part of their salary to purchase savings bonds. Series EE Savings Bonds earn a fixed interest rate for up to 30 years and are meant to be a long-term investment. The bonds are sold for face value, and there are penalties for redeeming them before a five-year waiting period.
