sick of it all

i am tried of my job it has become draining and a fight everyday with co-workers. I am tired of telling them over and over the same policies and procedures that haven't change since 4 years now. but i am being question everyday so i question them back, why you do why you do that policy states to do it this a way. i have had it I'm no longer going to question it but i will not jeopardize my job by doing what they ask i just won't question it anymore and let them be and stick to my job. they have a question they want answers i will point them in the right direction and in most cases i just won't answer and continue with my work.
