The job is very stressful due to the strenuous work but the pay from overtime and regular hours is very good, in my opinion. If you cant handle lifting heavy equipment/packages then don't pick here. If you want great pay and union then apply.
Work daily to make sure all the outgoing and incoming packages are not damaged. Forward to the correct sort and make sure the address is correct. Stop equipment when something happens and fix the error up and running again; it is a fast pace environment.
the post office is great if you're looking for a steady job but it is not a great place to advance in. It may be a great experience in corporate but as far as being a carrier and a clerk it is draining physically and mentally.
long hrs, a lot of physical work, wear and tear happens to your body after a while
