The environment can be very uncomfortable in some areas due to lack of climate controls. Constant back and forth between "the way it's always been done" and "let's try something new." Rotating schedule can be harsh. Sometimes it's hard to know who is in charge of something, as people get moved around a lot. Draft can eat into your time off, especially if your area is shorthanded. Communication from corporate seems to hit a wall before it reaches the technicians and operators; changes planned for years will seem abrupt to the people on the floor.
