The days are too short for the work that needs to be done
The easiest way to describe the situation is that the plant manager has an 1950 style of management. It's my way or the Highway. You work to make me look good. If you don't, you don't belong here, which means his staff will have to work the necessary hours to get the job done so that that he doesn't have to.
The workers themselves are miserable.
ProsFree Lunches only when the Plant Manager wants to promote himself
ConsLots and lots of BS
