The sell-off of Royal Mail is accompanied by the usual frothy hype – need private money, save public money for schools and hospitals, not to mention a blow-up Postman Pat smiling as the shares change hands. But the private money isn’t a donation. It comes at a cost – cutting back services, trimming costs, pressuring staff. It’s not surprising that many posties love their job – moving around, seeing people, being welcomed for what they bring. But that cosy sense of something shared has just been auctioned off.
