STRIKE rates in OECD countries vary widely from one year to the next, according to data compiled by Britain's official statisticians. Iceland tops the table of working days lost per 1,000 employees over ten years. There were no strikes in five of the ten years, but 1,571 days were lost in 2004, and over 1,000 in 2001. In Canada, by contrast, the rate was at least 100 days in each of the ten years.
