Is there any housekeepers out there?

I worked at a nursing home. I would like to know if it is possible to be able to clean be able to clean 50 rooms that have 1 to 2 beds (some are vent rooms), they all share a bathroom,3 large dining rooms (1 one of those is done twice a day), 2 employee bathrooms, 2 big shower rooms, 3 offices, 2 long hallways. In each room, you are expected to dust everything (everyday), sweep and mop the floor, empty the trash. Clean and scrub the toilets, sinks, fill the paper towel and soap dispencer.This is all done daily and in 8 hours and this is for one person. Some rooms have the patience in them and some don't. You have to work around the nurses as well.Can't clean the rooms if they are in their room eating, have to wait.Can any body do all this in one 8 hour day? I was just wondering as this is what my boss wanted me to do. I did half this for about 3 or 4 weeks and quit.My boss says that it can be done, but I can't see it happening and being done right on top of that. Can it be done?

If you don't do it, like you would at home, yes.
Start with the bathroom - chemicals into toilet and sink, let soak.
Dust everything that needs dusted - fast! Don't go slow...
Then clean the bathrooms and at the end wash the floors - and look where the dust or spots are - and out you are!

50 rooms? Oh, your boss is funny.
