You've just explained why this power isn't realistic to invoke. If you're a warehouse worker, can you afford the unemployment time long enough to find another job? Can your family?

I think yelling "I quit!" and slamming the door happens only in movies.

In real life most people first secure a new job and then resign from their current position.

To answer your question: no, my family cannot afford me not working for half a year as well. I believe this is the case for most of people not living with parents.
