In 1891, Irwin became the full-time Scottish organiser of the Women's Protective and Provident League, then in 1895 became the secretary of the Scottish Council for Women's Trades (SCWT).[5] In this role, she campaigned for the creation of the Scottish Trades Union Congress (STUC) and, when it was created in 1897, she was elected as its first secretary. However, Robert Smillie became unhappy that she did not focus much attention on the campaign for an eight-hour day, and in 1900, Irwin decided not to stand for re-election. However, she remained secretary of the SCWT, and frequently served as its delegate to the STUC over the next decade.[4] One of her main interests was the conditions for women who worked at home. It had been found that the economic condition of these workers was about as desperate as it could well be. There were occasional instances of ability to earn a decent living, but on the whole wages were extremely small, and the hours of labour extremely long.[6] The Glasgow Council for Women's Trades worked with John McAusland Denny to introduce a bill for the "compulsory provision of seats behind the counter for lady assistants in shops" that became the Seats for Shop Assistants Act 1899.[7] The Glasgow Council for Women's Trades under her chairmanship, also delivered lectures on the ethics of shopping. The meeting, chaired by Watson Reid heard that "There was no such things as a bargain, because if a thing was produced at less than the current rate somebody had to pay for it. The remedy for this sweating and ill-payment was exclusive preferential dealing with shops where fair conditions prevailed and the religious boycotting of any shop where these were not to be found" [8]
By the 1920s, Irwin was focusing much of her time on the fruit farm, developing model housing for workers there. She was elected as a fellow of the Royal Society of Arts, and was made a Commander of the Order of the British Empire in 1927. The SCWT dissolved in 1939, and Irwin died on 23 January the following year.[4]
