Explanation:

The organization of the Chief Labour Commissioner(Central) aka Central Industrial Relations Machinery is an apex organization in the country responsible for maintaining harmonious industrial relations mainly in the sphere of central Government. In pursuance of the recommendation of the Royal Commission on Labour in India, the organization was set up in April, 1945 by combining the former organizations of the conciliation Officer (Railways), Supervisor of Railway Labour and the Labour Welfare Advisor. It was then charged mainly with duties of prevention and settlement of industrial disputes, enforcement of labour laws and to promote welfare of workers in the industrial establishments falling within the sphere of the Central Government. 

In order to secure better conciliation, preventive mediation and more effective enforcement of labour laws, a scheme to further strengthening of the Central Industrial Relations Machinery was approved under the 6^th five-year plan. As a result, three more regions with headquarters at Guwahati, Chandigarh and Bangalore were created during 1981-82. Three more new regions with Headquarters at Ahmedabad, New Delhi and Cochin were created under the 7^th five-year plan in 1987-88. Two new regions Dehradun and Raipur with headquarters at Uttranchal and Chattisgarh respectively were created in the year 2005 by reallocating officers and staff within the existing strength of the officers and staff .
