That's pretty good anon. You can probably ask for a raise or promotion in the future. Probably.

I read online that you can usually get it if you do that + upper management likes having you around.

That's sounds pretty scummy. Maybe quitting is an option. Because they probably can't stay in business if the most productive workers end up leaving for greener pastures.
