Would you work in a place that doesn't have Saturday's off.

No

Well, as long as I don't have to go in to an office, perhaps I would because many times, at least on transactions, you have to work Saturdays though it is the day off. I don't imagine it is very different in litigation / arbitration if hearings are urgent.

I do. And it's called a t1 law firm.

Most places have Saturdays working.
