It seems to me that an easy way to stop people from quitting and suing would be for all the companies to create a sort of black list and name all the people (with DNI numbers) who did this sort of thing. So then in the future, when a business is considering hiring someone, they can check and see if this person has already pulled this stunt. If they have, well, so much for them being able to find another job in the future.
I'm probably thinking crazy, but it could work.
