I can't think of anything; it seems to have everything a typical company should have.
There were records of excessive overtime many years ago, but I don't know about now.
The on-site management trainee is basically a thug, using an intimidating management style that suggests he is ready to pick a fight at any moment.
I suspect he may have just completed his military service and not signed on, or perhaps the company never provided him with any management training.
This led him to believe that he has to be loud to manage everything. If an employee refuses to follow instructions, you can report it to upper management or write a report to report the misconduct.
Generally speaking, the standards on factory production lines really aren't very high, but this company left a particularly deep impression on me in the past.
