Everyone for themselves mentality among most departments, each departments blames the next. Management will lie to your face and actively work to see departments silo themselves off instead of collaborating. Bro-code culture, etc. Step on the toes of a VP, Director, or the Chief of staff and you won't be there long(they will literally berate you in front of your coworkers).
If you manage a rare pay raise without a position change, it will paint a target on your back.
