I want to know the answer to the following question:
In what year did Foxconn workers first unionize?
All the background I'm provided with is that "On December 31, 2006, workers at the Foxconn factory in Longhua, Shenzhen formed a union affiliated with the All-China Federation of Trade Unions, the Chinese government-approved union umbrella organization.". Is that enough to answer the question?
Answer: yes
