That's true. In my case I was not fired on the spot from a legal point of view. I had just to give up the keys, and my access to the company network was revoked, but legally I was still an employee for a while. And maybe you are right about me being a potential entrepreneur. It's something that's in the back of my mind, but so far I didn't find a business idea.
