Top down decision making, too many upper management positions, values not practiced, no career growth opportunities.
Toxic work culture full of fear. I know of several employees who have gone to HR about upper management verbal abuse, only to be retaliated again with PIPs. Those who went through this were eventually forced out.
Divisive CEO whose politics is blatantly obvious to the employees, and will pick and choose who and what to support based on his political leanings.
