Contract Labour Act Confusion: Does Security and Third-Party Staff Fall Under It?

Dear Sir/Madam, I am facing some issues related to contract labour. My first issue is whether security on contract comes under the Contract Labour Act or not. The second issue pertains to the canteen, JCB, bus, and staff of third-party service also falling under the Contract Labour Regulation and Abolition Act. Please help me to resolve these problems.

Contract labor refers to a worker who is considered employed in or in connection with the work of an establishment when hired by or through a contractor, with or without the principal employer's knowledge. This includes inter-State migrant workers but does not include an employee (other than a part-time employee).

Application of the Contract Labor (Regulation and Abolition) Act
Your security, canteen employees, JCB operators, bus drivers, and staff are hired in connection with the requirements of the establishment. Therefore, the Contract Labor (Regulation and Abolition) Act is very much applicable.

Primarily, all of them come under the CLRA Act of 1970 because they work on the premises of the Principal Employer (PE).

Sir, we hired an agency for the Mee plant, and they have 17 staff employees, all of whom are paid a good salary by the contractor. So, they also come under the scope of the Contract Labour Act. However, my one doubt is that they are all staff and not workers, and they provide services like running the Mee plant.

Can you please share some documents where services are defined so that we can easily identify who comes under the scope of the CLRA Act?
