Seafarers' Union of Burma
The Seafarers Union of Burma (SUB) is a trade union in exile from Burma. It represents an estimated 20,000-30,000 workers in the international shipping industry, many of whom work on Flag of Convenience ships and suffer from poor work and pay conditions.

Founded in 1991 by the Burmese seafarers who are in trouble and get contact with the International Transport Workers Federation (ITF) and its affiliated maritime unions around the world and supported by the Federation of Trade Unions of Burma (FTUB) in opposition to the government sanctioned "Myanmar Overseas Seafarers Association" (MOSA), SUB remains banned in Burma (Myanmar) but is recognized as the legitimate representative of Burmese sailors by other maritime unions, and is a member of the International Transport Workers' Federation.
