I've been working on IT security for about 5 years now, and I have been recently continuing my education.
I've been with my current employer about a year, but I'm constantly being offered more money to leave. Sometimes the upward of 20-30k of an increase.
I've gone up to the interview a few times and demanded more money than they were offering originally and have yet to be turned down. Although I have decided to stop through process before the interview several times.
I like my current employer and they are giving me room to grow with training however I feel that I may be tapped out on the technical side. I am only eligible for one more promotion before I'm maxed out as a tech.
The next option is management and this employer requires a 4 year degree for that. I have no degree and about 15 years total IT experience, so at this point I'm not sure a degree would help me for the amount of effort required.
