India’s labour law landscape has changed. Four new labour codes, the Code on Wages, 2019, the Industrial Relations Code, 2020, the Code on Social Security, 2020, and the Occupational Safety, Health and Working Conditions Code, 2020, bring together 29 central labour laws into a single framework. For employers, HR teams, lawyers and law students, the change raises practical questions about definitions, compliance and rights. To help with this, J.K. Verma has written a separate commentary on each code. This post introduces all four books and explains what each one covers.
