Long story short, I'm completely sure that my current salary is around 25% higher than what people with similar experience and skills would get in other companies in my area. At the same time I discovered that my coworkers' pay is on average much higher than mine.
I personally believe the reason behind this discrepancy is that when I joined I came from a different country and was not really knowledgeable about what I could have asked the company so I didn't negotiate hard enough during my interview process.
I was hoping that the situation could be rectified or at least improved during the first round of pay rises, but this took place just a few days ago and nothing significant came out of it. I tried to mention the issue to my manager but I basically shrugged it off by saying that he's not informed about the salary of other people and doesn't have much influence when it comes to pay rises.
Obviously changing job here would not help much, but this situation is leaving me with a very bitter taste in my mouth.
What else can I try?
