I'm in the midst of negotiating a salary with an institutional contractor that supplies personnel l for federal agencies.
My current salary is a GS-13, step 10. How much negotiating room do I have. Can I negotiate up to GS-14, step 10?
I don't want to overstep or seem greedy, but a full grade increase seems reasonable to me, because I've actually been doing GS14/15 level work, including supervising people, for a long time. I just didn't get paid or recognized for it.
