In China, two union officials have been detained for attempting to help workers at Jasic International organize a union. This is the latest development in the Communist Party’s attempts to repress labor activism in China; the government does not approve of grassroots movements or protests. Earlier this year when Jasic workers tried to unionize, the company proceeded to fire workers who had been engaging in collective activity. This incited protests from activists and students alike, many of whom have since been detained for their involvement.
