Your checks will be short. Keep track with proof of all your hours. Even then you might not get it back. Management will not like you for this. Management avoid or is incapable of its job. Hostile to the carriers except certain ones. Managers have their own sets of rules that contradict the other managers or those of the post office, which causes problems. Managers do not communicate to you or with each other and this leads to problems. The only manager who seems to want to be there is the one who is completely incompetent. Management practices CYA. It is necessary to ask the right questions to do your job right- they will not just tell you. They will pile on you for the slightest mistake in a heartbeat. You will not be encouraged in any way. You are nothing more than a tool. The vehicles are better cared for than you. You are not respected. It's sink or swim, but if you come up for air they'll smack you down.
This company has total job security but you are treated horribly. The amount of overtime you can work will make you stay for the money but it’s physically and mentally draining. Completely unsatisfying and unrewarding.
