After wirk francs mail illegal

I think there may be a bit of a language barrier or misunderstanding here!

It seems like you're trying to ask a question, but the sentence is a bit unclear. Could you please rephrase or provide more context so I can better understand what you're asking?

If you meant to ask "What happens after a work-from-home (WFH) employee's mail is illegal?", I'd be happy to help clarify.
