What kind of PhD research did you do? I considered going back for a PhD program focusing on simulation as it relates to discoverability within AI research, but kept ruling out it was a bad career decision and should be left as a retirement thing
This is such a bullshit thing to experience. I had a version of this where I took on extra work that I was interested in which became a new revenue stream but was told "let's see how you do and then we'll see about salary bumps". Never saw an extra dime from it. I used the experience learned to land a new job six months later with a salary bump while dumping the other job responsibilities. It's truly the only way to get that bump you deserve.
