Overview: Indian labour regulations balance corporate operational flexibility with workforce protection by strictly limiting contract labour in core business activities. Under Section 10 of the Contract Labour (Regulation and Abolition) Act, 1970 (CLRA) and Section 57 of the Occupational Safety, Health and Working Conditions (OSH) Code, 2020, core functions essential to an enterprise’s primary business model must be handled by regular employees. While ancillary support functions permit third-party staffing, core engagements are restricted to temporary demand surges or specialised, non-full-time tasks. Proper legal structuring ensures statutory compliance and prevents joint-employer liability.

Understanding the Legal Framework

Engaging contract labour is a vital strategic tool for modern enterprises aiming to maintain operational agility and control overhead costs. However, Indian statutory frameworks strictly restrict the deployment of contract personnel in primary business functions unless specific statutory criteria are fulfilled.

Understanding these legal boundaries is critical for regulatory compliance, mitigating risk, and avoiding expensive joint-employer liabilities where contract personnel could be legally deemed permanent employees of the principal employer.

What Constitutes a Core Activity?

Under Section 2(1)(p) of the OSH Code, 2020, a core activity is defined as any activity for which the establishment is set up, alongside any process that is essential or indispensable to its primary business output.

Furthermore, under Section 10(2) of the CLRA Act, 1970, regulatory authorities evaluate whether an activity is of a perennial nature (i.e., of sufficient duration and continuity) or carried out ordinarily through regular workmen to determine if contract labour engagement is prohibited.

Statutory Exemptions: Permitted Support (Non-Core) Services

To enable smooth commercial operations, the provision to Section 2(1)(p) of the OSH Code explicitly excludes specific ancillary support services from the definition of core activities. Enterprises can freely engage third-party contractors for these non-core operational functions:

Facility Management: Housekeeping, sanitation, gardening, and laundry services.
Logistics & Protection: Watch and ward (security services), courier delivery, transport, and loading/unloading operations.
Corporate Amenities: Canteen management, catering, guest house upkeep, and civil maintenance.
Intermittent Works: Operational duties that are unplanned, seasonal, or short-term in nature.

Statutory Exceptions for Core Operations

While engaging contract labour for primary business processes is generally prohibited, Section 57(1) of the OSH Code, 2020 permits temporary core engagements under three specific statutory exceptions:

Established Industry Practice: Where the normal, historical functioning of a specific sector relies on contractor involvement [Section 57(1)(a)].
Non-Full-Time Requirements: Tasks that do not demand full-time staff across standard working hours or extended periods [Section 57(1)(b)].
Surge in Workload: A sudden, time-bound increase in the volume of work within a core activity that needs to be accomplished within a specified timeframe [Section 57(1)(c)].

Frequently Asked Questions

What is the statutory scope of Section 10 of the CLRA Act?

Section 10 of the Contract Labour (Regulation and Abolition) Act, 1970 empowers the appropriate Government to prohibit the employment of contract labour in any process, operation, or other work of an establishment, particularly where the work is perennial in nature, essential to the business, or is ordinarily performed by regular employees.

When does registration under CLRA or the OSH Code become mandatory?

Registration is mandatory for a principal employer engaging the prescribed threshold of contract workers on any day during the preceding twelve months. The threshold is 20 or more contract workers under Section 7 of the CLRA Act and 50 or more contract workers under Chapter XI, Part I of the Occupational Safety, Health and Working Conditions (OSH) Code, 2020.

What are the legal risks of misclassifying core activities?

Misclassifying core business activities as support services may violate Section 10 of the CLRA Act and Section 57 of the OSH Code. Such non-compliance can result in statutory penalties, prosecution, and judicial directions requiring the principal employer to absorb eligible contract workers into regular employment.
