So I left a job as a KP for a backshift job working in a factory. Within 3 shifts I can feel this has negatively effected my mental health massively. It isn't just the backshift but the bordem. I'm 90% sure this job is not for me and I've already contacted my previous employer to see if the job is still available. I found that working as a KP was more social and rewarding whereas being in a factory during the late hours of the night is just depressing. Would you suggest I tell my manager today that I do not think I am the right candidate for the job and will not be staying? I also need to be trained so I feel it would be best to avoid any training so I and they don't feel like I owe them anything. Thoughts?
Edit: I spoke to the manager when I went in today and was honest about my feelings which went well. They responded well and were more happy than anything that I told them so they can contact one of the other interview candidates to come in. Honesty is definitely best in this situation instead of forcing myself to stay and being miserable which would have inevitably led to me quitting on the spot on being in a much worse position!
