In December last year, violence against garment workers began after Cambodian unions called a national strike. Workers were demanding an increase in the minimum wage to USD 160 per month. As protests continued, the police and military responded with violence on January 2 and 3, killing at least 4 people and injuring almost 40. Among those who were arrested with violence is Vorn Pao, union leader of the Independent Democratic Informal Economy Association (IDEA). In February, he smuggled a letter out of prison.
