we are providing security services on contract to various establishments . We have provided services to one of of the P S U for more than 20 years and now the contract is discontinued For all practical purposes the said PSU have been paying all statuary liabilities like Minimum Salary P.fund ESI contributions and fixed working margins to us to maintain the unit. Some of employees have been working with the same organization since last 20 years. Now my query is for payment of Gratuity to these employees. Who shall pay gratuity Principal Employer or the contractor. As a contractor our understanding with the principal employer is all the statutary payments is to be paid by them but now the management is not willing to pay .
