The document discusses different forms of employee voice in industrial relations, including self-management, employee involvement, and employee representation via trade unions. It argues that while union membership has declined, collective representation through trade unions remains important for regulating social and economic interests in the workplace. Union-management partnership strategies that involve cooperation and problem-solving have potential benefits, though critics argue they can be fragile. The document concludes that effective representative employee voice should be supported by public policy and contemporary human resource management.
