I was working for a small temp company when I was just starting. I was hired to do some server work, but ended up developing a system to automate most of it. So my job became more developer. However I was still getting paid as a server admin (and the low end of that to boot). So I asked to get paid more appropriately. After asking they gave me a really small boost, pretty much what you'd expect just as an annual increase. So I went to my manager at the company, said I get paid pretty low here i'm going to think about looking for other opportunities. About an hour later, I had the boost I wanted.
