I was illegally terminated from my job in Kolkata, how do I file a complaint with the Labour Commissioner?

You can file a complaint with the Labour Commissioner of your state under the West Bengal Premises Tenancy Act 1997 governing industrial disputes, which empowers the Commissioner to conciliate and refer disputes for adjudication. Prepare a written complaint detailing your appointment, termination date, grounds you believe are illegal, and the relief sought, and submit it to the Deputy Labour Commissioner or Conciliation Officer in Kolkata. The Commissioner will issue a notice to the employer and attempt conciliation; if it fails, the matter is referred to the Labour Court or Industrial Tribunal. The Calcutta High Court has held that the Labour Commissioner must act within a reasonable time and cannot keep matters pending indefinitely. If your establishment has fewer than the threshold workmen, the appropriate government may still intervene through its labour department. You should retain your appointment letter, salary slips, and termination order as supporting evidence.
