So I was hired 2 years ago as an assistant director. My colleague was also hired (similar experiences) at during the same time as an associate director. Are roles have been exactly the same now, are roles are slightly changing but still have the same amount of responsibility. I’m aware that she may get paid more. Is this something I can bring up during my yearly salary negotiation? And if so how should I bring it up without comparing myself and speak on the unfairness?
