It doesn't have to be equity. If they wanted to, they could put in their employment contract "If you say anything bad about McDonalds, you owe us $1000." What is the ex-burger-flipper going to do? Fight them in court?

Like a fast food employee would have equity in the company. Please, let's at least be sensible in our internet ranting.

i got f-all equity, I was flipping burgers for minimum wage.

Also, whatever fries left in the bottom of the bag. That’s corporate property buddy.
