I am personally not convinced by your reasons to shift to the IT/ITES industry. In my opinion, the challenges for an HR person are far greater in industries that are labor-oriented. However, HR, as a profession, is industry-independent since it pertains to the lifecycle management of employees across the organization. The only difference lies in the framework of policies and processes used to manage people. This difference may even exist between different companies within the same industry.
What I mean to convey is that one's contribution to the organization, as well as personal growth as a professional, is undoubtedly more substantial through continuity within the same industry. Concepts like 'HR as a Business Partner' are frequently discussed. How can one become an effective business partner without a clear understanding of the financial aspects of managing a business? Each business vertical varies from the others in this regard. Therefore, transitioning from manufacturing to IT/ITES requires not only learning about their HR policies and processes but also understanding the business management in an IT company. Trust me, it is a significant undertaking not worth pursuing, especially when the same effort could propel you further in your current environment.
Change, solely for the sake of change, is rarely beneficial unless undertaken after thorough research, reflection, and analysis.
