Pay. I am under paid, my boss knows it, and there is nothing she can do about it. The Compensation team dictates everything, but they don’t know my skills, or how hard I work. They put your resume on a pay scale and It’s a huge disappointment. I don't get paid for my proficiency, I get paid at the bottom of the scale because of my years of experience.
Also, the PTO isn’t very generous, and there is no opportunity for growth. There is no opportunity for career advancement.
