It is well understood that full time jobs don't always require, well, your full time. But at certain times you might run into a bottleneck which requires you to work extra hours. Playing the employment juggle is fine as long as you don't run into any serious challenges, and especially not in all positions simultaneously. For front end, this could maybe work if your job requires a light touch and mostly off the shelf parts with a tiny bit of glue. But good luck trying to debug an elusive issue that has something to do with parallel computing in your distributed services while in another job you were just assigned to replace a piece of the stack in a legacy system. I personally don't think there's anything morally wrong about working several jobs, as long as you can deliver the full capacity when needed. I've been avoiding doing this myself for this reason. When the narrow straights hit, I need to be able to fulfill my position.
