people people, a raise is something you get at one employer, not by switching jobs, that is technically not a raise, at least how I see it.
Biggest raise I got was about 20% last year, am expecting about a 15-20% raise here pretty soon, to put me in line with what I should be making.
If we are talking switching jobs, then I went from 30k a year + small bonus (about 4k) to about 70k a year (after the initial training) job, so about 100% this was when the economy was doing very well though 🙁
