The ninth revised edition of Industrial Relations and Labour Laws presents a comprehensive, analytical, and critical exploration of labour law and industrial relations in India. Spanning 35 chapters, the book delves into key themes including the trade union movement, collective bargaining and workers' participation in management, the constitutional and jurisprudential framework, laws governing industrial disputes, trade unions, and standing orders, social security and wage legislation, statutes relating to factories, contract labour, child labour, and inter-state migrant workers. The book also covers the four labour codes: industrial relations, social security, wages, and occupational safety, health and working conditions. This edition integrates general principles with contemporary issues and challenges, supported by relevant case law to equip students, practitioners, and professionals with practical insights and legal clarity. Designed to meet academic and professional needs across disciplines, the book aligns with the syllabi of LLB, LLM, MBA, MPA, MSW, the Company Secretary course, and Master's and diploma programs in industrial relations, personnel management, human resource management, and labour law. It also serves as an indispensable reference for HR and personnel managers in public and private sectors, labour department officials at central and state levels, presiding officers of labour courts and tribunals, trade union representatives and labour lawyers.
