The trade union for public and welfare services (JHL) went on wildcat strike to oppose the "marketization" of Palmia, a municipally-owned service enterprise. The right-wing leadership of the city is attempting to reorganise 50% of Palmia so that it must participate in tendering-out, which will lead to substantial wage cuts for the workers. The seizure of subway and tram transport by striking workers proved to be a powerful weapon in the struggle against the bosses.
On 18 August 2014 over 10,000 port truckers in Ningbo, China, went on strike, not having had a raise in over 8 years. The strike lasted almost a week, with management offering a 12% raise. It involved nearly the entire trucking fleet of Ningbo, which is China's 3rd busiest port and the world's 6th busiest. During the strike, the port was paralyzed and ships were diverted to Shanghai.
