you're considering going back to a company that has already laid you off?
if you're not happy w/ your current company, it's better to find another company.
as an hiring manager, if i saw someone jump back and forth to the same company, it would raise concerns. why? it also suggests you don't challenge/grow yourself. so unless you plan to stay (and not get laid off again), you're digging a hole for getting the next job.
Had to make this into a thread, it was posted by @11YHgpWP-1xmu. 100% on point.
