Wage steps

I just got a new job and I have 4 years and they told me that I was step 4, so I'm assuming it's 1 step per year.

With zero years of exp you are on step one. So if you have 7 years under your belt, you are on step 8. There is no step zero, so you are always one step above your total years.

Hmm.. I kinda wondered about that. I wonder if I got put on the wrong step. Do you happen to know what the rate for step 5 is?
