When you start as a letter carrier, your life is at the post office. You have zero time off (including Sunday’s) and work until management says you can leave. You will make great money but not have much time off. You will have to wait until someone retires for you to move up to become a “regular”. Then you’re going to do the same route every single day, over and over. You will also only have 8 weekends year .
This job is just a stepping stone to something better. My opinion, nothing to get comfortable with, my opinion. The money is good due to excessive overtime but fairness is not easy to come by in this work environment favoritism is.
