Employers need to remember who is doing the work that keeps the place spinning.
You'll be replaced by someone better and cheaper. No one is as important as you think you are.
There's a shortage of journeymen in my trade, but if we all quit, they'll bring in guys from the Philippines who will work for 75% less.
My $4 million/year boss can quit tomorrow, but the company will keep going, and won't miss a beat.
I've quit several high paying jobs. Never been fired, big deal.
If you were a slave and tried to quit, you wouldn't be alive to find another master.
Like that other guy said, work 10-12 hours a day 7 days a week on your own farm or 40 hours/week and have a comfy life. I choose comfy.
