Low pay. I once was a professional.. until everything I went to school for and have gained by working in the field was undermined. I am told what to do. There is no thinking, since I was threatened to be terminated for doing so. (And my job requirement is to do some thinking lol.) No communication. No meetings. Nothing. Less than nothing.
If you are not part of the top 6 or so people you are expendable. Expect to be disrespected. You are a dummy. They have long noses to look down upon your idiot self... with a smile mind you. ;) The power dynamic is closed shut and there is no room for movement. Expect your self esteem to float away and confidence to be sapped.
Raises? Nothing based on your work, but a communal 4% and not every year. I am probably underpaid by 30% for my skill set.
