Israel’s national trade union, Histadrut, has announced a general strike will take place on Sunday in response to Teva Pharmaceuticals’ plan to lay off 10,000 workers. The world’s largest producer of generic drugs will be at a standstill all of Sunday, and according to the union’s chairman, the entire Israeli economy will stand in solidarity for half of the day, including government services, banks, and the airport. Histadrut is about 750,000 workers strong, and although their power has weakened somewhat in recent years, its massive base is still able to wield power over major areas of the economy.
