NYT video featuring Wu Guijun

This is a remarkable, must-see video displaying Shenzhen-based labor activist Wu Guijun assisting workers cheated out of social insurance contributions for decades.  I had the chance to meet the very impressive Wu in Shenzhen in 2015.  He himself spent a significant amount of time in jail for helping his fellow coworkers before the charges were dropped.  After his release, he decided to be a full-time labor activist.
