Also, it's up to you how you get your home cleaning done. You can hire a once-a-week maid service (it's not that expensive). You get to decide how clean you want your toilet bowl to be. It's your choice, though, and the only people you have to answer to (if applicable) are your family.

Having someone who can turn off your income and damage your professional reputation tell you that you have to drop everything at 4:00 and clean a toilet is a different thing altogether. That's ridiculous.

Again, if you're a real partner/owner (0.05% equity does not count) you do a bunch of undesirable work (including cleaning toilets, if it makes sense) because the buck stops with you. If you're an employee, you simply should not stand for this.
