The Workmen's Compensation Act, 1923 aims to provide relief to workmen and their dependents in cases of accidents arising from employment. It covers workmen in hazardous occupations such as factories, mines, construction, transport, etc. The Act defines key terms like dependent, employer, workman and provides that employers are liable to pay compensation for work-related injuries or deaths. Employers must pay compensation for both temporary or permanent disablement resulting from accidents or occupational diseases arising during employment. The Act also covers contract labor and prohibits contracting out of liability for compensation. Authorities are appointed to enforce the provisions of the Act.
