My Pvt Ltd company was locked out in July 2015, and before closing, my 5 months' salary was also due. Management instructed all lower staff to stay at home and come when called. However, all senior staff continued to work regularly even before the company closed, and they are now at the head office. When we found out and went to the head office, our MD did not want to meet us. In my company, the lockout was due to a workmanship strike for a salary hike. What should we do in these conditions to receive our full and final settlement? Where should we go in Kolkata for assistance? Please help and guide me.
