Dear Suresh,
In your case more than the manpower contractor i.e. Matheson Helios, it is MNC that is at fault.
The provisions of Payment of Wages Act, 1936 and the Payment of Wages Karnataka Rules, 1963 are mutatis mutandis applicable primarily to the contractor and in case of his/her default to the principal employer.
It is the joint responsibility of the Contractor and the Principal Employer to disburse wages in time, and record the same in the ‘Register of Wages-cum-Muster Roll’, wherein either the principal employer or his authorised representative is required to certify as follows:
“Certified that the amount shown in column No ______ has been paid to the workmen concerned in my presence on date _______ at ________ am/pm”
For non-payment of salaries and wages in time, you may approach the labour officer of your area. In case if he refuses to intervene, try obtaining certificate to this effect and then send the lawyers notice.
While recommending course of litigation, I warn you to be careful of your career also. As such you are on contractor's role and in no time principal employer can fire you. Nevertheless, legally your case is strong and law is on your side. In case if you file a suit then as a punitive measure, tell lawyer to recommend termination of contractor's licence of Helios and Matheson. Let court give its verdict on that count too.
By the way, why are you hiding the name of that MNC? If that MNC does not have scruples to follow the laws of the land then should you not bring it to the notice in the public domain? Let that MNC get the taste of social media. You could have raised this post anonymously and disclosed which is that MNC.
All the best!
