I have a co-worker who does this, and everyone likes him, especially the boss, since he will jump on anything and get it done. He also seems to work really long hours and weekends, even though he has a family. He also does not seem to want to negotiate for a raise. I've chosen to not be likey coworker and so far I've been promoted, gotten 10 and 15 percent raises, etc. I do tend to rub coworkers and leadership the wrong way sometimes, but that's a trade-off I am fine with. I would rather be happy with my work hours and well paid than well liked.
