as I already mentioned having reserves is indeed very important

in my jurisdiction there are for example some excellent guaranteed income insurances covering various situations. they won't pay forever, but they'll pay. income replacement due to health issues is covered by normal social welfare in my jurisdiction as well

all of those things you mentioned happen regularly to employees. they are harder to let go, sure, but employers have a lot more leeway to make your job hellish enough to force a resignation, or if the economy is really bad overall they can throw their hands up and say we're cutting divisions of the business with no objections from the law in most places. sure you can go to your work council (hope they are on your side) about it, or to the union (hope they have time for you and you're lucky enough to have enough evidence to win the tribunal) or the lawyer (hope you have a legal assistance insurance and are ready for years of process and fees). employees without a savings buffer are similarly vulnerable in these circumstances

the biggest reason to stay an employee if you can consult instead where I am is really the unemployment benefits you can get, but that now takes up to 10 months to actually start paying out due to how understaffed the government is. so again, best have some reserves. the next biggest reason is you hate paperwork
