Ah - got you. Well, who knows...

In my Beeb days, most broadcasters/presenters were not classed as "permanent" staff, but were employed on a regular, renewable contractual basis which meant that they could work elsewhere as they chose and therefore earn money outside the BBC. "Permanent" staff like myself couldn't do this - and our contract stipulated that everything that we did - such as writing a book - was the exclusive property of the Corporation, even if it had no connection whatsoever with the Corporation! So, in those days, DJs could do work for the BBC but also freelance outside its walls. Whether such free arrangements exist for Smooth Ops contracted people I haven't the faintest idea.
