My job is not a relaxing one, I work from 5 am to 2, 3, or sometimes 4 in the afternoon. I'm on my feet 24/7 and constantly moving and picking up some heavy stuff. Is it safe to work in such a stressful enviroment? I am 7 weeks and a day. My boss has me working in a stressful position, should i asked to be placed at a less stressful position like cashier?
