COLD callers are the bane of our existence. They interrupt our dinner, usually trying to sell us stuff we don’t want.

Of course, for the million-plus people on the other end of the line in the “factories of our time”, those calls put food on the table, and in the case of BBC Three’s hit docusoap The Call Centre, make money for the likes of Nev Wiltshire.

You may remember him, the largerthan- life chief executive of Swansea’s largest call centre who runs his 600 staff with a firm hand, but has a broad sense of humour.

“What sums up my management style?

Some say I’m barking orders. Some say I’m barking mad, but there’s life in the old dog yet.”

Now Nev and the team are back for a new run, and in the opener he gives his managers a pep talk, tea girl Hayley takes a staff member to task, and Abii reveals the secrets of HR.
