The Postal and Telegraph Clerks' Association (PTCA) was a trade union in the United Kingdom for workers in the post office and telecommunications industries.
The union was founded in 1881 as the Postal Telegraph Clerks' Association, amalgamated with the United Kingdom Postal Clerks' Association in 1914 to form the Postal and Telegraph Clerks' Association, and in 1919 amalgamated with the Postmen's Federation and the Fawcett Association to form the Union of Post Office Workers.
Notable figures in the leadership of the union included the women's officer, Edith Howse.
[1] Lynes was elected as general secretary in 1919, but before he could take up the post, the union was merged.
