Since you have already completed your MBA, consider which area you would like to focus on in the future. Is it statutory compliances, training, performance management, recruitment, industrial relations, employee engagement, etc.?
Focus on Statutory Compliances
If you are interested in statutory compliances, you could enroll in a course that covers everything from analyzing a salary slip to the final stages. Before enrolling, it would be beneficial to do some groundwork by self-studying the components of a salary, including taxable and non-taxable components, and analyzing 2-3 salary slips from different companies. This will provide you with a brief overview.
