The work is not hard just poor management and unnecessary drama among co workers. As any other job do your job and go home. Do not try to make friends just be polite and keep it moving. Never try to do anything extra for management because they do not appreciate it.
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.
