This book makes a major contribution to the continuing legal and historical struggle for equal pay in Australia, with international references, including Canada, the UK and US. It takes law, history and women’s and gender studies to analyse and recount campaigns, cases and debates. Industrial bodies federally and around Australia have grappled with this issue from the early-twentieth century onwards. This book traces the struggle through the decades, looking at women's organisations activism and demands, union ‘pro’ and ‘against’ activity, and the 'official' approach in tribunals, boards and courts.
