The union was founded in Sheffield in 1897 as the National Association of General Railway Clerks, although it was a narrow decision to found the union. The railway companies were strongly opposed to trade unions and two earlier attempts to form a clerks' union had failed and, discouraged, the organisers decided by a majority of only one vote to try a third time - this time successfully. In 1899 it was renamed the Railway Clerks' Association (RCA), and in 1951 it adopted its current name.
