I quit my last job without notice because I had one lined up (but it turned out I couldn't start immediately) and in retrospect my rent situation would have been a lot better if I'd just scrupulously covered my ass for a month. And I'm lucky enough to have the kind of job where people call back within 12h of me submitting a resume but that's exactly because I do the kind of 100% essential jobs that have a coinflip's worth of shitty bosses and the kind of pay that leaves you paycheck to paycheck if you've had bad enough luck and/or life choices in a particular year. I guess I could've just called places and got some temp work from the first employer to offer but then I'm still having to cover my ass but now against the devil I don't know while learning a whole new set of policies that I'm only gonna use for one month before I'm learning the next ones. If you're in a secure enough position in your life that you can just quit because you have a good enough balance of savings and demand for your skillset then please take a moment today and practice gratitude to whatever entity or lack thereof that you attribute your good fortune to.
