Depends where and who's laws. In the Uk, max 2 hours in the seat and minimum 30 mins break. Simple. When I was in the middle east a couple of years ago, 3 hour stints were common but usually with much longer breaks afterwards (even the next 3 hours on nights!). Here in Switzerland, it is not uncommon to work a little over two hours (although with at least one change of position) with another two after a 20 minute break. All legal in their own way.
