"35 hour week"

They started that in France in 2000.  

"The main stated objectives of the law were twofold:

To reduce unemployment and yield a better division of labor, in a context where some people work long hours while some others are unemployed. A 10.2% decrease in the hours extracted from each worker would, theoretically, require firms to hire correspondingly more workers, a remedy for unemployment.

To take advantage of improvements in productivity of modern society to give workers some more personal time to enhance quality of life."

"Critics of the 35-hour working week have argued that it has failed to serve its purpose because an increase in recruitment has not occurred and that the reluctance of firms to take on new workers has instead simply increased per-hour production quotas"
