Early Life and Background

Eddie Dempsey was born in April 1982 and raised on the Woodpecker Estate in New Cross, South East London. Growing up in a working-class area with a strong Irish community, he was surrounded by the realities of industrial labour from an early age. His upbringing played a significant role in shaping his political identity and sense of solidarity with working people.

His father worked as a deep-sea sailor, a profession that exposed Dempsey to the challenges faced by manual workers whose lives are shaped by demanding schedules and physical labour. This background helped instil a strong sense of class awareness that later defined his approach to trade union leadership.

Entry into the Railway Industry

Dempsey entered the railway industry around 2008, taking up roles that included station work and later train driving. These frontline positions gave him direct experience of the pressures faced by transport workers, from safety concerns to pay disputes and job security.

Unlike many leaders who arrive from academic or political backgrounds, Dempsey’s authority within the union movement was built on lived experience. His early involvement in workplace organising allowed him to gain trust among colleagues who saw him as one of their own rather than a distant administrator.

Rise Within the RMT

Eddie Dempsey’s rise within the RMT was steady and rooted in internal union democracy. After serving as a branch activist, he moved into national leadership when he was elected Assistant General Secretary in October 2021. This role placed him at the heart of union strategy during a period of mounting industrial tension.

In April 2022, he became Senior Assistant General Secretary, further expanding his influence within the organisation. His ascent culminated in March 2025 when he was elected unopposed as General Secretary, succeeding Mick Lynch and signalling continuity in the union’s militant stance.

Leadership During Industrial Action

During the 2022–2023 rail strikes, Dempsey emerged as a prominent public figure, frequently appearing in media interviews to defend workers’ demands. His communication style was direct, unapologetic, and firmly grounded in class politics, which resonated strongly with many union members.

At the same time, this visibility placed him under intense scrutiny. While supporters praised his clarity and honesty, opponents criticised his refusal to soften his rhetoric. These strikes cemented his reputation as a leader willing to confront government and corporate power head-on.

Political Identity and Ideology

Eddie Dempsey openly identifies as a socialist and has consistently framed labour struggles in terms of class conflict. His political thinking draws heavily on Irish socialist traditions, reflecting his family heritage and long-standing involvement with Irish workers’ organisations.

He has also been outspoken on national and international issues, including advocating a left-wing case for Brexit and opposing British military involvement abroad. These positions have attracted both admiration and criticism, reinforcing his image as a principled but polarising figure.

Controversy and Public Debate

One of the most debated moments in Dempsey’s public life relates to a 2015 visit to eastern Ukraine. The trip later became controversial due to its political context, and it has been repeatedly raised by critics questioning his foreign policy views.

Dempsey has consistently described the visit as humanitarian and anti-fascist in nature. While the issue remains divisive, it highlights how his career has been shaped not only by industrial action but also by wider ideological debates within the British left.

Life Outside the Union

Despite his high-profile role, Eddie Dempsey maintains a lifestyle closely aligned with his working-class identity. He has spoken openly about living in council housing in London, reinforcing his public image as a leader who shares the conditions of the people he represents.

He is also known for his passion for football, supporting Millwall FC and Celtic FC. These affiliations further connect him to the communities and cultural traditions that shaped his early life.

Complete Career Overview

From railway worker to union general secretary, Eddie Dempsey’s career reflects a clear progression built on workplace activism and organisational loyalty. Each stage of his journey has reinforced his reputation as a leader shaped by experience rather than abstraction.

As General secretary of the National Union of Rail, Maritime and Transport Workers, he now oversees one of Britain’s most strategically important unions, representing workers across rail, maritime, and transport sectors during a period of rapid economic and political change.

Conclusion

Eddie Dempsey stands as a powerful symbol of modern trade unionism: respected for his authenticity, criticised for his uncompromising politics, and central to debates about the future of organised labour in Britain. His leadership style challenges traditional political norms while appealing strongly to workers seeking firm representation.

Whether viewed as a champion of the working class or a controversial ideologue, his influence on the labour movement is undeniable. As industrial relations continue to evolve, Eddie Dempsey’s legacy will be measured by his impact on workers’ rights and the strength of collective action in the UK.
