A lot of workers in technology are getting paid in equity. For many, it makes it more than acceptable. It's not really anyone's place to tell someone else that the way they're making money is unacceptable without knowing all of the details.
I put in 60-70 hour weeks routinely. I work at companies I founded and own. I don't make overtime. Is my work schedule unacceptable?
What is the percentage of equity between 0% and 100% that makes working above 40 hours per week "acceptable"? Who picks?
