putting yourself in front of people who will give you a salary commensurate with your effort is not Gen-Z flakery.

sitting tight with a company who have demonstrated they do not value your efforts is big Boomer energy.

the days of sticking with a company and expecting them to do right by you in the long run are so long past we aren't even in the same century.
if a company shows they don't care about your efforts, believe them.

all the best
