I once worked for an ex marine that did this. The company wasn't big, there was only one bathroom. Once a week someone would clean the break area and the bathroom. It was rotational. Everyone would clean their areas in the rest of the building. Every Friday at 4:00. We were a production based business but everyone was kind of mentally checked out by that time on Friday anyways. He did it mainly because he was cheap. It was easier to pay employees to clean for an hour than to hire a cleaner to come in. Honestly, it's not a bad thing to do. It gave you a break from work-work and you could zone out while turning your brain to weekend mode.
