It is a known fact that if your employer is not willing to give market rate comp, it is on you to get the market rate on the market.
But owners knows most of us are lil bitches who loath any discomfort or change. So he is able to attricion us.
If you can, you should be getting raises after 2-3 years per employer. They should he actually offering you more to keep you tbh but that's a sorry for a different time.
