No matter what job you do at the USPS, it will be one of the most difficult jobs you will ever do. The mail is heavy and pretty dirty and sometimes you have to deal with angry customers who are unhappy with their service. If you are in your early 20s, you might enjoy the job because you can build a career there and get great benefits. But you will have to be a non career employee for about 3yrs or more before you become permanent. Some supervisors are very condescending and talk to you like a child, others are not helpful. You will make money because you will work very long hours and work 6 days a week mandatory. It's not for everyone. Its definitely not for someone who actually wants to have a life. And don't let me get started on working out in the elements! Rain, sleet, snow wind and butter cold.... get used to it because the mail never stops being delivered.
