Wot abaht the workers?
Of course the average drone doesn't get it. By "it" I mean anything. Still they ought to know that by connecting to the company network at any level, they risk having their personal equipment subject to examination or even confiscation by the relevant authorities, be they lawyers, police or even (Thank God not here) the VAT men.
Which is why I wouldn't even give the company the MAC address of my phone, let alone connect it to any of their multifarious networks, even the so-called "Guest" network.
