So is it just a case of pointless job creation? Porter won't have it, though he believes there are some questionable appointments in the public sector. "There's an element of truth in it, particularly in certain desk jobs. Managers, for example, can sometimes get assistants - but tradesmen can't." He does agree that his job title might sound a little baffling to an outsider. "A lot of people think it's a pen-pushing desk job. So when people ask, I just say I deal with maintenance and repairs, it makes life a lot easier."
