> But that doesn't make any sense. Ostensibly, you were being paid market rate before. If you were to leave, maybe you'll be able to get a raise at another position, maybe not, but the other employees at your company don't change that.
When it comes to money, humans are generally irrational in their decision making, mostly biased towards emotional decision making.

This actually happened to me when I was 16 years old. I started working at fastfood job making $4.90/hr, WA state's minimum wage. I was a very strong worker, and was offered a position as a manager a few months later. I politely declined (read: my mother told me I was dumb to sacrifice my education in order make an extra $1.00 or so an hour).
Eventually I was making $5.15 an hour through a series of wage increases due to good reviews. Then the Federal government raised minimum wage to $5.15/hr. I went to the store manager and asked for a raise. My argument was that my wage increases were do to my performance and seniority. Any unproven new-hire would start making the same wage as I do. They did not see it that way, and declined to provide me with a compensation increase.
The feeling was irrational. I still made my wage, and new employees wages didn't come out of my pocket, so it had no impact on me. Still, I felt that my salary should reflect the value I bring to the company.
I ended up putting in my two-weeks about a year later when they promoted an inept person to manager.
