Have some evidence that your position pays better. HR departments will buy salary reports that under report sources like BLS (that they use to justify your low wages to themselves), so you better bring some good stuff. When a substantial change in responsibilities or work environment is made bring it up. This might get you a token 1% or so which your company will just take out of next year's 2% raise. Going someplace else works great. Expect 10-30% more unless you are already at the top of the pay range for your job and market.
