> even worse, additional responsibilities for the same pay FWIW, and I say this acutely aware that I'm of the "don't give them what you don't owe them" tribe, additional responsibilities for the same pay are how I got the broad skillset that got me to the point where I'm a principal developer with a hand in every part of our project--which is, in addition to no-complaints compensated, genuinely a lot of fun. I took on those responsibilities as an investment in myself; admittedly the key was finding high-value, high-leverage responsibilities, but it was for me more than for my current employer. Few enough people are going to pay you to learn something on their dime if you don't already show a ton of promise. Broadening your skillset is, IMO, how you get to the next job.
