I have a few questions that came to mind after reading the Communist Theory FAQ:
1. If the Big Industry will see an expansion once it is freed from private property, will this mean the government ordering people to do certain jobs?
In communism? No. Since there will be no government. But I suspect that you are talking about the dictatorship of the proletariat, i.e., the transition to communism. With a raised class consciousness, which was necessary to establish the dictatorship of the proletariat, most workers will do what needs to be done because they want to contribute.
2. What if someone just stopped working?
It depends.
3. Do I get to do the occupation I want to in communism? For instance, what if all I wanted to do was teach art or music?
I do not see why you could not restrict your activities, but in communism, people will generally be doing lots of different things, because they can do that in a communist society, as opposed to a capitalist society.
