Sally McManus and Michele O'Neil exit after the longest ACTU leadership tenure in half a century. Their legacy includes right-to-disconnect laws, wage theft criminalisation, and a rebound in union membership.
Australia's two top union officials will leave by the end of the year, a surprise announcement made Monday to key union figures. Sally McManus, secretary of the Australian Council of Trade Unions, steps down at the end of August. President Michele O'Neil follows a few months later, staying on to help with the transition to a "new generation."
McManus and O'Neil took over in 2017 and 2018. They were the longest-serving ACTU leaders in more than half a century and the first all-female team to run the peak union body. Their tenure spanned the pandemic, a surprise Coalition election win in 2019, and Labor's return to power in 2022. That shift opened the door for a wave of workplace law changes the pair had pushed for years.
Among the legislative wins: the right to disconnect from work outside hours, criminalising wage theft, same-job same-pay rules for contractors, and minimum conditions for gig workers. Labor last week revived the Fair Work Court, a long-standing union demand. McManus, in an interview Monday, said almost a decade was a long time to hold the role. She noted the COVID years counted double.
Union membership, which had fallen for decades, showed a small rebound. The rate stood at 13.1% in 2024, up from a record low of 12.5% in 2022. O'Neil said membership growth played into their decision to step down now, with the momentum handed to a new generation. The Australian Bureau of Statistics will release its next survey later this year.
The biggest internal challenge came from the Construction, Forestry and Maritime Employees Union, a male-dominated powerhouse. In 2024, after allegations of criminal infiltration, the ACTU suspended the CFMEU's membership. The decision drew criticism from both sides. McManus revealed she had to change her routine and live in different places due to security concerns.
Under McManus and O'Neil, the ACTU shifted its strategy from strikes to legislation. With fewer members and laws that made striking harder, the focus turned to winning rights that applied to all workers, not just union members. The 2009 Fair Work Act still contains provisions that favour employers. The union movement made gains on bargaining and enforcement.
McManus named cost of living, artificial intelligence at work, and wealth inequality as key challenges for her successors. Real wages have fallen over the past five years, and many Australians are still struggling. The transition begins with McManus's departure at the end of August. O'Neil will stay on to help hand over to the new leadership.
Australia's union movement represents roughly 1.6 million workers. As of 2024, more women (around 853,000) hold union membership than men (around 726,000). The Australian Nursing and Midwifery Federation is the country's biggest union today, representing about 356,000 nurses, midwives and care workers.
