I'll add my experience to this. I was a part-time casual during the summers while I was in college. I made really good money but also worked 6 days a week 50hrs. The job is much harder than most people think it is. As a youngster with no seniority I was given one route per day, always different, along with bits off of others to cover for people that were off. Typically, you will never be near a driving route and will get the most difficult, ie largest, routes. I also did collections after my routes..driving to various blue boxes and getting mail to the distribution center. I have a great deal of respect for the guys that do it. As far a a full time carrier....knowing a bunch and having family members that were I can say right now they are working guys extremely hard. There is mandatory overtime for pretty much everyone. Taking vacation is extremely difficult and they dont get that many holidays, despite what people think. Currently, they are receiving a lot of pressure and are not hiring nearly enough people. Most of that is due to increasing costs and the mandate that they cannot make a profit. You also have to remember that you have a 6 day work week with a rotating day off. Its great when you have a Saturday followed by a Monday but not so great when it is Wednesday and you work Saturday. I would also add that typically the communication between mgmt and the carriers is atrocious with a great deal of resentment on the carriers part. Again, I have great respect for the guys and the institution. The post office is amazingly efficient and puts Fed Ex/UPS to shame when it comes to error less delivery. However, it is a tough life.
