As per Contract Labour act,the contractor and principal employer are the parties between whom the contract is established and executed. Now that if the agreement between the parties if exists and the statutory compliance being done in accordance,then employee will be getting the benifits or compensation.
If the contract date expires and there was no extention granted by the principal employer, then question arises that why the contractor continued working?. Secondly Why contractor was allowed to work by the principal employer too?
Under such circumstances, if any incident happens and employee is injured or death occurs during work at work place, the principal employer stands responsible as even if there was no work order or any othe permit etc,the incident happend in the premises of principal employer and during work hrs, hence the principal employer can be held responsible towards compensating the employee.
It is however the right of employee to get compensation in any case under natural justice.
