Work Restrictions, No OT and no more 12 hour days??

April

So I had my 16 wk appointment today. Everything is going fine. I brought up some lower back pain I’ve been having at work, which I feel is normal. My doc said I need to stop working over 8 hours and only 40 hours a week! I’m nervous how my work is going to take this. I’m also not sure it’s totally necessary. Would love to hear your thoughts.
