It is my considered and humble opinion that any question of law can be understood and answered in the right perspective only through one's own meticulous reading of all available judgments, even if contradictory, on the question. That's why I intentionally refrained from providing pinpoint answers to the queries of both Vidhyadhar and yourself.
Analysis of Relevant Judgments
Now, let us make a brief analysis of the following judgments on the issue as far as known to me:
1. Cominco Binani Zinc Ltd v. Pappachan [1989 LLR 123 - Kerala High Court]
2. Madras Fertilizers Ltd v. Controlling Authority under the P.G Act [2003 LLR 244 - Madras High Court]
3. Mettur Thermal Station v. Appellate Authority under the P.G Act [2012 LLR 1160 - Madras H.C]
In the first case, the questions before the Court were the liability of payment of bonus and gratuity to the contract labor employed in the factory of the Principal Employer. Since the claim was based on the settlement between the contractor and the union of contract labor, the honorable Kerala High Court refused to fasten the liability on the PE as he was not a party to the said settlement based on the narrow interpretation of sec. 21(4) of the CLRA Act, 1970.
In the second case, the honorable Madras High Court undertook a detailed analysis of sec. 21(4) of the CLRA Act with reference to the term "wages" as defined under sec. 2(vi) of the Payment of Wages Act, 1936, particularly elaborately interpreting clause (d) of the definition and ruled that the PE is liable to pay gratuity to the contract labor by virtue of the vicarious liability imposed by the section in case of failure by the contractor.
The third case followed the ratio decidendi of the second case law.
Therefore, the inescapable conclusion is that a contract employee working for a principal employer can stake a strong claim for gratuity directly from the PE at the time of termination of his employment if he is otherwise qualified in the event of the contractor's failure. Since "gratuity" also falls within the ambit of the definition of wages under the PW Act, 1936, and the vicarious liability created by sec. 21(4) of the CLRA Act, 1970 on the PE for payment of wages and other benefits applies to the payment of gratuity too, it is advisable for all the PEs engaging contract labor through manpower agencies and other contractors to include the amount of gratuity in the CTC of the contract labor on an annual/pro rata basis irrespective of the length of service.
