At which point, it's worth pausing to reflect on what all this actually entails. Thanks to referrals by both jobcentres and private-sector Work Programme providers, it's about people effectively working for nothing, not only in charities and the public sector, but in huge retail chains. Thanks to the legal action launched by Cait Reilly, we all know about Poundland. Asda, Boots, Argos and TK Maxx, and the Arcadia group (including Topshop and Burton) are also involved. Hats off, perhaps, to Sainsbury's and Waterstones for announcing that they have ended their involvement with this kind of work experience, but if you want an indication that workfare may be turning into an immovable part of the private-sector economy, consider last night and today's blizzard of outrage about a Tesco ad placed on the Jobcentre Plus website. It's for nightshift workers in East Anglia, who will be paid "JSA plus expenses".
