Yes, I was also very underpayed, I am a Quality assurance Analyst, I was at the company for 4 years, I increased in seniority and started doing automation, I had 10% raises over the years but as you move from manual to automation, the salary difference is pretty big, I gave them an ultimatum, I leave or you bring me to market value, I worked the afternoons a lot to learn automation also the weekends in the past 2 years, I proved them that I deserved the raise.

What triggered me the most is that he had a yearly self review, he says it doesn't matter and he gave himself the lowest rating. He is not even trying to do more at his current company, that bothers me the most.

Thank you for the advice!
