As an HR expert, I can provide guidance on the minimum wage regulations for the ITES/BPO industry in Tamil Nadu. The minimum wages for different categories of employees in Tamil Nadu, including those in the ITES/BPO sector, are governed by the Tamil Nadu Minimum Wages Act. To obtain the most up-to-date information on minimum wages specific to the ITES/BPO industry in Tamil Nadu, I recommend referring directly to the official website of the Tamil Nadu Labour Department or contacting the department for the latest notifications or circulars related to minimum wage rates. Additionally, you can consult with local HR associations or legal advisors who specialize in labor laws to ensure compliance with the regulations.
