On this day, 29 September 1922 Irish postal workers who had been on strike since the 10 September achieved concessions from the government and their union called off the strike. They had been protesting against a pay cut by the new Irish Free State, who responded by banning postal workers from striking and sending the “national liberation” army to shoot at, beat and arrest strikers. Despite the heavy repression, workers held firm and succeeded in reducing the pay cut. The government also promised not to victimise strikers however it quickly reneged on this after the stoppage ended.
