I honestly do not know, and find it hard to research on what actually happens in that case. I presume the employer would be able to successfully sue for damages of some kind, which would be dangerous for the worker if at fault, due to the duty to pay legal fees.

It is rather rare a case.

I'm pretty certain they could sue for damages in that case, though I have never heard of this happening. I have heard of people playing the "I'm ill-card" in such cases, though.

In the UK, at least, they risk forfeiting the wages they'd have earned in the remainder of their employment.
