Then in various jurisdictions you have to prove that. In court. See item 1 of http://www.nytimes.com/2006/03/28/world/europe/28iht-letter.... and this sort of thing is not limited to France.

The US setup of at-will employment looks just as weird on that side of the Atlantic, I'm told, as theirs does to us.

I can't tell you what the setup is with being able to close down a business. It wouldn't terribly surprise me if there are legal hurdles to that too.
