It really depends. I did not at all when funding ran out from a university position. The lab tried its hardest to get funding and keep the positions. Part of that though is they had rules and regs such that I got termination contracts for some years before the end. They don't mean termination per se but they basically mean they do not not have funding to do it again next year. My lab eeked out a few more years by managing to get some small grants and projects and such before the end. Also though the university pays poorly so I basically started making better money once I had a job again. Had another one where the guy who owned the place made poor decisions and needed a scape goat to bs to his clients about. ie he could not say he was cheap and directed me to reformat and install laptops under assumptions the former employees backed up properly. Pretty bitter on that one. One was for covid and like the company was literally doing the keep the lights on thing so totally understandable and of course there was gov action to soften things. Most of my other jobs were straight up contracting so it was expected. So I only have one bitter situation and even then its more like. F that guy and I hope he gets whats coming to him.
