Has anyone had experience with enforcement of employment non-compete agreements in Switzerland? Is it common to have a XX months ban to work for competition after leaving, which is partially paid by the employer? I have a contract of this type and was headhunted by a competing firm. Now, what are the chances that if I leave, my employer will pursue a legal action based on the non-compate cause in the contract?
Would appreciate an input.

check out this Thread on the same subject for a start. There might be some others too - try a search. Somewhere there might be some legal links.

This in German

Our company removed the non-compete clause from our contracts as they considered it to be unenforceable.

PS: After having read gata's post below, I just wanted to clarify that I assumed non-compete after having left the company. Naturally doing work for a competitor while still employed would most probably result in termination on the spot. (But then who would do that?....OK, I don't need to know)

We have the same. One colleague got caught and he and the company agreed a "mutual termination" of his contract
