Getting kudos for being a "team player" often means that they are deliberately stringing you along to see how much they can get out of you without paying you more. Management and HR is not your friend. You can have good relationships with them, but you need to define reasonable boundaries and stick to them. You can do more than the job description, but at some point you gotta say, "I've proven what I can do, and would love to do more, once you formally give me the role where this new work is appropriate."
