Born near Chipping Sodbury in Oxfordshire, Hayward served in the Royal Air Force during World War II. At the end of the war, he became the Labour Party's secretary and agent in Banbury. In 1949 he moved to Kent, where he began a friendship with local MP Arthur Bottomley. The following year, Bottomley ensured his appointed as the party's London assistant regional organiser, and in 1959 he became organiser for the Southern region. He served in this role until 1969, when he became National Agent. In 1972, he narrowly defeated Gwyn Morgan to become General Secretary of the Labour Party.
As General Secretary, Hayward opposed entry to the Common Market and supported unilateral nuclear disarmament. He strongly supported the Presidency of Salvador Allende in Chile, and after its overthrow became friends with Hortensia Bussi, Allende's former wife. Privately, he was very critical of the Labour Party leadership's lack of response to the counter-revolution. In the 1980s he opposed the Militant tendency, but was reluctant to expel its supporters from the party. He was fiercely opposed to the Gang of Four, who led the split which formed the Social Democratic Party.
In 1982, Hayward retired from his Labour Party positions.
