No, it's his company, if anything, I'd enjoy working for him. But only if my work contract clearly states that I need only put in X hours per week into work.
I worked in a startup, became the right-hand of the boss and owner, and then he'd slip into work only once per week. I did this for three years, my pay was... ok, but I didn't see the ability to develop any further or earn any more and eventually quit, and started my own company a few months ago.
I would've really appreciated if he would've done more, so that I could have focused more on actual technical work and not administrative or management work. Mabye I would've even stayed, I don't know.
Then again, I am very different than most people, so maybe this is just a very lonesome opinion...
