Long excessive hours. Some supervisors & definitely upper management have Big heads w/ little brains on their shoulders. Union doesn't stick up for or represent employees too well. yeah, they'll defend you, but how hard depends on the Union Steward representing you, & ultimately the company ends up winning regardless. Forget knowing what a weekend is. YOU WILL be scheduled for every one of them regardless. & just general stuff wrong that annoys employees that you'll find with any manufacturing facility.
