Well, it depends what kind of work you're in. If you're working in an office or something, going on a rant about what "real" work is, might just make your higher ups think that the job isn't a good fit for you. If you're doing anything else, you'll probably just get a raise.

I've been working on just keeping my mouth shut and working my ass off at work. It's hard to do sometimes given that there are some morons I work with, but it's been getting me good results so far.
