How brave should I be?

I’m a restaurant manager, have been for the last 6 years, but now I’m working 6 days a week not including bits I have to do from home, unpaid for anything over 45 hours and suffering at the bottom end of all the current logistical challenges, I’ve long since had enough.
I’ve close family members leaving much higher paid jobs than mine to do the same thing and a step dad who’s trucked all of his life who have encouraged me to follow this route having had a chat with a few of them and one of our drivers about it.
