EU referendum, brexit and the aftermath

The draft legislation unveiled late last week would “severely reduce” the attractiveness of hiring people from abroad, the parliamentary committee said, by favouring people – including EU citizens – already living in Switzerland.

So their idea is to draft a bill to encourage swiss employers to employ swiss people. I wonder what form this would take? Surely many businesses are going to ignore it and take the cheaper/more available labour anyway. It would have to be a very real and pursuasive incentive.
