All I do is PMs and I hate it

Hello all I know ima get hate for this post but I just got hired at a new corrugated plant 3 months ago and every Tuesday and Thursday and now Fridays since were slow I’m forced to lube the machine for 8 hours and do mechanical inspections it was nice at first because it’s easy but I can’t fuckin do it anymore it’s so mind numbing and boring time goes so slow. The plant I come from had a small team of operators they called the lube team and would always lube on pm days while I did repairs. Is this normal I don’t think I can’t take it anymore might have to find a place where I can learn and work hard again rather than just greasing everyone is new here and we can’t stand it so far.

Edits: I feel like I should add in not new to this industry I have 3 year experience prior to this and one year was field service so I’m quite familiar with the corrugator
