The latest reality TV show hit our screens last week – The Call Centre. It’s based in the Swansea call centre business, Save Britain Money. The motto of the firm is a simple aphorism – ‘happy people sell’. And in this documentary, which at first appears to be an Office-style comedy show until a creeping realisation hits that it’s actually real, the employees do seem to be pretty happy (that is apart from the ones who seem to be victims of low-level bullying). And they do seem to sell. So is Nev Wilshere, CEO of Save Britain Money, onto something?
