Higher management are clueless and will talk down to staff and use intimidation and threats to shut down any concerns or issues you may have.
You will receive file notes for the smallest of things ( seemingly dependant on the mood of the higher management on the day).
they are constantly finding new ways to micromanage every second of your day, and if you ever have to leave your desk ( even for work related reasons) You will be stopped and questioned why you are not working
