Thomas Jackson (9 April 1925 – 6 June 2003) was a British trade unionist and is best remembered as the General Secretary of the Union of Post Office Workers who led 200,000 members into a 47-day strike in 1971, the first national postal strike.
Jackson was born in Leeds, West Yorkshire.
Aged 14 he began work for the GPO as a telegraph boy.
He spent three years (1943–46) on wartime service in the Royal Navy.
Upon his return he became a postman, and later a sorter, during which time he became involved in the affairs of the Union of Post Office Workers.
He became a member of its executive council in 1955 and in 1964 was elected national officer.
In 1967, he became General Secretary, a role he held until 1982.
He was instantly recognisable to the public for his luxuriant handlebar moustache.
