"Lefty" also seems misguided. What if the factory is also my house? Why should I give my house away to the people that I hire to work there?

That's a bizarre circumstance. Usually anything that looks like that actually involves somebody doing the actual work and hiring assistants. In which case the circumstances really don't change, aside from the assistants get the full value of their labor. 

Remember it's not the property itself in question, but the value produced by the operation of that property. If you're some really weird factory owner who lives under the machines for some reason, your living circumstances don't change. It's just that the wealth generated by those machines go in full to the people working them. You can still live under the machines, you just have to work them sometimes and actually create value in order to make a living so to speak. You could always give the machinery over to those workers. But if you decide to lock people out, then yeh, there will probably be an altercation, since those machines happen to be the way your recently liberated employees make a living. This would probably become one of those unhappy circumstances revolutions tend to create, in the same sense that employees of the crown found themselves in a bad place during the American Revolution despite most of them being law-abiding and honest people. There are wrinkles in any instance where a society moves from one method of organization to another. 

A more practical weird circumstance I thought up while trying to imagine a more realistic petite-bourgeois scenario than yours was the circumstance of a factory I worked at a couple of years back. It was a small place owned by a woman who was wealthy, but not full Mr Burns bourgeois. In a revolutionary circumstance, that factory would naturally become the purview of those who actually worked on the floor. Thing is though, the place was full of dogs, because she was a big part of the local rescue community. Those dogs would be hers of course. In the completely unrealistic scenario of a clean-break revolution where everything changes over a short period of time and no actual blood is spilled, there would probably be an awkward moment where she has to come into the factory she no longer has control of in order to get her dogs.
