Pros
Decent money, good vacation time. Decent health insurance. Sick leave. You can get a job by taking the test and scoring high. You don't need a degree and you can earn more than a lot of people that have degrees.
Cons
Long hours. Unfair treatment. Favoritism. You have to overlook a lot of crap. The rules are interpreted to suit the ossaision. Rural carriers get paid by salary, no matter how long the workday can be, the pay remains the same. You will have to do a lot of physical labor every day. The general public thinks this is not possible and that we are overpaid to ride around in cars all day and just stick mail in boxes. We do all our own sorting and loading. Some of us have to provide and maintain our own vehicles. Customers think they have the right to disrespect us. They are quick to complain if we make a mistake, yet we might fix a lot of their mistakes in a days work and they won't ever know about it.
