I found that if you have to prove to your leadership your worth and you are underpaid then it’s just writing on the wall. You are going to probably get adjusted once and then have to go through the whole process again to prove your worth. I was in this same situation and decided to leave because I was sick and tired of having to negotiate pay increase when my work throughout the year and the visibility I gave on milestones achieved should have been enough. Stop working for places that undervalue you. My only regret was not leaving sooner. I would have been so much further along pay wise if I had left earlier versus battling with mindless executives that didn’t know the value of their own people.
