AND THEY'RE UNPRODUCTIVE FOR MOST OF THE SIX:

In February the nurses switched from an eight-hour to a six-hour working day for the same wage - the first controlled trial of shorter hours since a rightward political shift in Sweden a decade ago snuffed out earlier efforts to explore alternatives to the traditional working week.

"I used to be exhausted all the time, I would come home from work and pass out on the sofa," says Lise-Lotte Pettersson, 41, an assistant nurse at Svartedalens care home in Gothenburg. "But not now. I am much more alert: I have much more energy for my work, and also for family life."

The Svartedalens experiment is inspiring others around Sweden: at Gothenburg's Sahlgrenska University hospital, orthopaedic surgery has moved to a six-hour day, as have doctors and nurses in two hospital departments in Umeå to the north. And the trend is not confined to the public sector: small businesses claim that a shorter day can increase productivity while reducing staff turnover.
