I had an obfuscated title and job description. If a more main stream title and job description had been used, it would have been obvious that I was paid below market rate. I don't think that was on purpose, but I lost income due to this. At one point I was paid under the minimum rate that HR had set for my position.
My supervisor had no idea what I did and I took directions from others in management that I did not report to. I was not given any mentor-ship regarding my career path. When I had identified another department that I thought was more along my career path, management actively blocked my movement and told me that they were protecting me, because the other team had bad management. Assuming my management team was honest, it is a terrible spot to be in knowing you are not where you should be and the department you should go to is in chaos.
I was frequently worked to exhaustion and took massive hits to my overall health. There was no work life balance and although the word was thrown around sometimes, it was always lip service. Work had to get done no matter the cost. The hard hours were not even recognized and no thank you's were given. Many times I had worked 70+ hour weeks and even got scolded for not getting enough done.
