I know this isn’t quite what you’re meaning, but it sounds like you’re saying “don’t quit so they can fire you instead.”
If you quit you don't get EI, you don't get any kind of payoff from the company, and it looks worse than "I was let go due to company downsizing" when interviewing.
It's good in theory, but in practice you can't count on that money, and you must find another job ASAP to feed your family.
I found a better job and I will quit because it's way faster for me to get out of my current company's mess.
I knew a guy at Apple that was given 60 days to find a new job or move to LA or be terminated. He found a job in another team just as his 60 days was running out.
