As a person who manages people, I cannot fight for your raise if YOU don't fight for your raise.
I cannot tell you how many times where something like this happens. I tell my higher ups, "Sarah should get promoted and increase her salary" and then my bosses go up to Sarah and she responds all limpdick like, "I like my job and I'm happy."
God damn it Sarah! Flex a little. Talk about how you see a opening you want. Stop being a keyboard warrior on Work Reform and actually SAY IT OUT LOUD. Share your wins! Brag about your value to the company. Demand your worth to MY BOSSES TOO.
It's not a single person who makes these decisions. It's multiple people.
Nobody is going to hand you shit if you're timid about it.
