Sometimes strikes have better worker protections than mass quitting.
Also, usually besides "not doing the work", strikes usually involve engaging in some practices (e.g. picket lines) to prevent or inhibit anyone else from "doing the work". That's not true of mass quitting.
I've never been in a position where I could earn a pension. But, vestment of employer contributions to my 401k used to be contingent on years of continuous employment. Quitting and being rehired would have resulted in losing all funds that hadn't yet vested.

You can get lethal effects from nicotine, alcohol, bleach, ammonia, and many, many combinations of chemicals that are available with, at most, age verification.
