Company not paying my dues. How do I recover my money after resigning?

If your job was of a supervisory nature as per your 'Senior' Designation, we suggest that you should send the Company a Legal Notice by way of Regd. AD and Speed Post for payment of your salary and other dues within a stipulated time period or else you shall initiate legal proceedings.

In case the payment is not released by the company within the time period, you can then file a civil suit against the company for recovery of salary and other dues as debt. The amount payable to you is in the form of debt on the company and you can hence initiate an action for recovery of this debt. The court fee is about 2-2.5% of the amount you are claiming.

On the other hand, 

If your nature of duties would come within the purview of "workman" irrespective of ostentatious designation adorned upon you, then you can file a case before the authority under the Delhi Shops & Establishment Act (if you are working in Delhi), who is the Deputy Labour Commissioner.
