Outside North America and Western Europe, the legal status of union security agreements varies even more widely. In New Zealand, as of 1988, the closed shop was compulsory where a union organized the workplace. In the Philippines, various types of union security agreements are permitted under labor law. In Mexico, the closed shop was mandatory until the early 1990s, when a change in federal law permitted the union shop, agency shop, or no agreement at all. But because of the political ties between unions and the governing party in Mexico and other ways in which Mexican law favors established unions, the closed shop is essentially still the norm.
