There are two separate conditions under which I'd work 70+ hour weeks:<p>1. I'm being paid a multiple >=1.5 of my base salary for each hour over 40<p>2. I have vested, real equity that isn't trivial, which I define as entitling me to real decision making authority in the organization, a share of profits that when combined with salary are sufficient pay me quite well and that offer protection against significant dilution<p>My view is that anything outside these conditions is more or less an exploitation relationship. It doesn't matter what one expects will be the value of options or other factors. 70+ hour weeks is almost all of one's wakeful hours spent outside of fulfilling biological necessities (sleep, eating, hygiene). It deserves significant compensation.
