Gormley was born in Ashton-in-Makerfield, Lancashire in 1917, one of seven children, and became a miner at the age of fourteen. He was an active trade union official and became a committee member of National Union of Mineworkers (NUM) in 1957. He served as general secretary of the North West region (comprising Lancashire and Cumberland) from April 1961 and joined the national executive in 1963. He was appointed an Officer of the Order of the British Empire in the 1970 New Year's Honours. He was a lifelong fan of Wigan Rugby League Football Club.
In 1971, he was elected as leader of the NUM and presided over the national strike that began on 9 January 1972. The strike lasted for seven weeks and the Middle East oil crisis caused widespread power cuts. Emergency measures were used to economise on electricity by reducing the working week to three days. After much negotiation the strike was resolved on 25 February 1972 with a 21% increase in pay and concessions won by the miners. Miners moved to the top of the UK's industrial wage league, having previously been seventeenth.
Only two years later, NUM members voted again for to strike and stopped work on 4 February 1974. Prime Minister Edward Heath called a snap election on this issue, asking the public, "Who governs Britain?" Gormley tried to persuade the National Executive Conference to postpone the strike until after any election, but the strike went ahead. After the election brought in a new Labour government, the union's demands were met. The new National Coal Board "Plan for Coal", launched that year, was extremely ambitious in its scope of expansion of the coal mining industry.
In 1981, Prime Minister Margaret Thatcher threatened to break with the plan and close 23 pits. A ballot for strike was held if the government closed pits contrary to the Plan for Coal. A strike mandate resulted with a 87.6% majority. The NUM Executive had a clear mandate for strike action if the government breached the Plan fo Coal agreement. When a national strike was threatened, Thatcher backed down; many miners went on unofficial strike in the year, but Gormley rejected calls for a national strike. He left his post in 1982 and was replaced by the more left-wing Arthur Scargill. In 1982, his last-minute appeal got miners to accept a Government offer of a 9.3% raise, rejecting Scargill's call for a strike authorisation. When asked what he had achieved during his period as President, he replied, "Everyone wants to be related to a miner".
One of Gormley's long-term legacies which affected the 1984–85 strike was his role in the wage reforms of 1977. The reforms paid miners a wage proportionate to the output of their region. This gave Nottinghamshire miners the highest wages of all and so they were very reluctant to go on strike in 1984, when few of their pits was under threat and those miners had high wages to lose.
Another key matter was that two ballots of the NUM membership had rejected these reforms, and Gormley responded by declaring productivity schemes now to be for the regional committees to decide, with or without a regional ballot. When this was challenged in the High Court as a violation of union rules, the court upheld Gormley. This confusion over when the NUM needed to hold a ballot became of huge importance during the 1984-5 strike, when Scargill tried to mimic Gormley's methods and make a national strike into something on which regional committees could decide.
In 2002, the BBC uncovered that Gormley had worked for Special Branch (a Government National Security agency, part of the police force) by passing on information on extremism within his own union. A former Special Branch officer made this allegation and said that Gormley "loved his country. He was a patriot and he was very wary and worried about the growth of militancy within his own union". The BBC claimed, "Special Branch was talking to more than 20 senior trades union leaders during the early 1970s".
