Upper management is clueless about how to fix problems they already have, on top of adding new problems regularly.
Middle management is equally clueless, and just parrots upper managements' edicts.
This company has serious communication problems. You will be made to work mandatory overtime, with no room for life events unless it's an emergency. Meanwhile there won't be enough work for the people who are there, for months on end. Employees will work slowly and make intentional mistakes as a reason to have something to do and fix later. Management will be unable to secure parts and equipment necessary for project completion, and then punish employees for missed deadlines. Rules, regulations, policies, schedules, and standards are made up on-the-fly, and are inconsistent in the extreme. Blueprints are constantly incorrect and require modifications by technicians and team leads. Engineers copy old blueprints for new projects, incorrectly, and without necessary modifications. This leads to an attitude of "Make it wrong now, make it work later" which employees will later be blamed for the high amounts of necessary rework.
Experienced workers will be replaced by new untrained employees who make legitimate mistakes. These mistakes will be fixed by someone else, and the new employee will not be given the opportunity to learn how to improve. Every stage from raw metal, to finished product, is a carousel of fixing the repeated mistakes of the previous stage.
Internal politics and an "Us vs. Them" attitude from management leads to huge drops in employee engagement. This, combined with the constant threat of being fired without warning for problems that the employee has no control over, or often, no information about, leads to many employees wondering "why are we even here?"
You will never get a raise regardless of any skill-gap between you and your coworkers. You will also be fired immediately for knowing what one of your coworkers makes. Despite this being illegal.
