The union was founded in 1952 with the merger of the Post Office Controlling Officers' Association, the London Postal Superintending Officers' Association, and the Central Telegraph Superintending Officers' Association, the three unions have co-operated since 1916 in the Federation of Post Office Supervisory Officers. Initially named the Association of Post Office Controlling Officers (APOCO), it was joined by the Postal Inspectors' Association in 1959, and in 1968 decided to rename itself as the Post Office Management Staff Association (POMA), to reflect its broader membership.
The union affiliated to the Trades Union Congress in 1966. It was also affiliated to the Federation of Post Office Unions, the National Federation of Professional Workers, and the Postal Telegraph and Telephone International. In 1981, it took its final name, the "Communication Managers' Association".
