They don’t care about their employees, they will over work you and sometimes you actually have to fight with them over the money that’s yours. I wouldn’t recommend it if you have bigger goals in life. I had no time for school, family or anything else.
The USPS is a honorable job who’s purpose is to serve the community. The benefits are excellent for full time workers. However the assistants ( or part timers) do not qualify for disability, unemployment or sick leave.
