A 2009 report by the Center for Economic and Policy Research, a group funded by various labor groups and foundations, examined policies in 22 countries "ranked highly in terms of economic and human development." It says in the first paragraph that the U.S. is "the only country that does not guarantee that workers receive paid sick days or paid sick leave," but it goes on to say that neither Canada nor Japan has a policy for financial support for short-term leave, for an illness such as a five-day flu. Those countries do have social insurance that would cover some of the pay for an employee needing 50 days off for cancer treatment. Those are the two scenarios examined in the study.
