Mansour Osanlou teaches Tavaana’s Labor Rights and Labor Organizing course and is one of Iran's most respected union leaders. Mr. Osanlou is the former president of the Tehran Bus Drivers' Union (Sherkat-e Vahed) and has been imprisoned for a total of more than five years for his trade union activities. In December 2005, Mr. Osanlou organized a major independent strike in Iran, protesting the government's refusal to recognize the Bus Driver’s Union and its demands concerning work conditions and housing and education benefits. Despite the arrest of Mr. Osanlou and hundreds more workers, the strike continued for months and attracted widespread domestic and international attention. Organizations including Amnesty International, Human Rights Watch, and the International Transport Workers' Federation called for Mr. Osanlou's release and condemned his treatment by the government. Osanlou was released in August 2006 but was again arrested in November, then released the following month. In June 2007, Mr. Osanlou traveled to Europe, where he addressed the International Transport Workers' Federation and visited the Trades Union Congress and the International Trade Union Confederation. The next month, upon his return to Iran, he was again detained, then sentenced to five years' imprisonment on charges of "acting against national security" and "propaganda against the state.” In 2010, his sentence was extended to six years. He was released from prison in June 2011 and now resides in the United States.
