WORKERS on London's underground rail network begin a strike on Monday September 6th, while across the channel French workers are also on strike in protest at attempts by the government to change the retirement age. Both countries come fairly high on the list of countries that lose working days to labour disputes. South Africa, where Cosatu, a federation of unions with some 2m members, has been on strike since August 18th, also scores highly on this measure. But all of these places are left in they shade by the Canadians, who lost 2.2m working days to strikes last year. Greece, which is also fond of striking, does not appear on this chart as its numbers are not comparable.
