Why is "Labour rights in China" trending?

Wikipedia Overview

As the economy of the People's Republic of China has developed, issues of labor relations have evolved. Prior to the Chinese economic reform, Chinese citizens were only allowed to work where they originated from. Since 1978, when China began labor force reforms, the overwhelming majority of the labor force were either working at state-owned enterprises (SOEs) or as farm workers in the rural countryside. However, over time China began to reform and by the late 90's many had moved from the countryside into the cities in hopes of higher paying jobs and more opportunities. The only connection between the countryside and the city soon became that there was a huge floating population connecting them. Independent unions are illegal in China with only the All-China Federation of Trade Unions (ACFTU) permitted by the Chinese state and the Chinese Communist Party to operate. China has been the largest exporter of goods in the world since 2009 and the largest trading nation in the world since 2013. As China moved away from their planned economy and more towards a market economy the government has brought on many reforms. The aim of this shift in economies was to match the international standards set by the World Trade Organization and other economic entities. The ACFTU that was established to protect the interests of national and local trade unions failed to represent the workers, leading to the 2010 crackdowns. However, these strikes were centered around foreign companies.
