My advice is to go in with a positive outlook. Make the best of your learning, and do your best to remember what you're taught. There are many opportunities within the Postal Service, look into all positions before you choose one. Certain careers are not meant for everyone
If you finish early as a rural carrier, you can leave and still get your regular evaluated time.
Of you are new coming in, you may not get proper training before management starts to move you around to other Postal jobs.
Literally the worse job that I’ve ever had. They expect you to be available to work any schedule, to handle any amount of labor, to complete job duties that are not in your job description and to deal with managements abuse for no benefits to start and minimum wage (basically). The turn over rate is 2 or more years meaning “ you’re at their disposal”. I wouldn’t recommend this job if you have a family to provide for.
