Consider your job is going good. How much of a salary increase motivates you to change jobs? When I mean salary - let's look at TC/year. And < 50%, I meant to say. Greater than 50. My bad.
How often do you switch jobs to get ahead? It used to be two years.
I think 2-4 is ideal.
<50% = all of the above
I did mention that it was a typo. Thanks for letting me know eitherways..
