Dear Colleague,
This questions is answered several times in this form by our colleagues and you may read it for full understanding.
As far as Contract Labour Regulation and Abolition Act 1970 there are 2 basic requirements: 1) The Principal Employer has to apply and get Registration Certificate for engaging contract workers in his establishment as and when 20 number is reached by adding the number of contract workers engaged by his contractors in total 2) Each contractor who are engaging 20 or more contract workers has to apply and get the License under the CLRA 1970.
As far as BOCW Act the employer has to apply for registration:
―employer‖ in relation to an establishment, means the owner thereof, and includes—
(i) in relation to a building or other construction work carried on by or on behalf of a local authority or other establishment, directly without any contractor, the chief executive officer of that authority or establishment;
(ii) in relation to a building or other construction work carried on by or through a contractor, or by the employment of building workers supplied by a contractor, the contractor;
The objective of BOCW Act is:
An Act to regulate the employment and conditions of service of building and other construction workers and to provide for their safety, health and welfare measures and for other matters connected therewith or incidental thereto.
The CLRA Act's objective is :
n Act to regulate the employment of contract labour in certain establishments and to provide for its abolition in certain circumstances and for matters connected therewith
So both CLRA and BOCW Act are applicable for Building and other Contraction Activities or for establishments who do such activity.
The Number 20 under the contract labour act and the number mentioned in BOCA and other acts need not be same. For instance in case of Interstate Migrant Workers Act the number is 5 or more workers. Each Act is operating with certain basic purpose and objective and the numbers are fixed by Government keeping those objectives in mind.
