FYI: People working for American companies in Japan are covered by US Civil Rights Law

For the Americans (and anyone else) working in US multinational companies: The US Equal Employment Opportunities law applies even in Japan, and if you are being treated unfairly (and that includes being given contract employment while Japanese get regular employment), you can bring a charge under US law and call for US labor commission mediation even in Japan. Fact is, people working for American multinational companies have double labor rights/civil rights protections — both American and Japanese. And apparently the American government links to the civil rights authorities of other countries/unions like Canada and the EU. More on the USG EEOC site. Further, HANDBOOK FOR NEWCOMERS, MIGRANTS AND IMMIGRANTS TO JAPAN has been helping people define their terms and anchor their arguments. Happy to hear.
