Last year, the company I work at didn't give me the annual evaluation (so no raise). I contacted them in January telling them that they skipped me and that inflation and prices are at an all time high, they scheduled it for late March.
March came and they offered me a 6% raise, barely covering inflation to which I replied “that's all? seems low”. They tried guilt tripping me since I've been WFH for over 2 years and everything. I have done my homework (unlike in the past where I just said “thanks” to a shitty raise) and knew my market worth. I told them what I needed and what the average income is for my position to which they smugly asked “Yes, but in what city?”, to which I promptly replied “Irrelevant, it says WFH”.
They said they'd get back to me in a couple of days after doing their own research. They offered me a 15% raise and a monthly bonus to help with working from home (money to pay for bills and what not) and said future raises/salary corrections will follow.
TL;DR: Know your worth and don't say yes to the first offer.
