I'd say dealing with anyone in HR
Sometimes the long (12 hour) days make it tricky to balance work and home life.
Clueless and senseless director, who has zero understanding of what's he is doing. Whishy whashy at decision making. Lack of material. Product going out the day is covered in metal pieces to cover the screw ups. Unqualified and over pumped supervisors who don't care about being there.
Clueless director and management. Disfuntional and self screaming supervisors. The employees don't want to be there but they need the paycheck
