Hi Ganesh,
I would like to help you with this, but first, could you please tell me what type of industry you have entered? With my limited knowledge, I have provided some topics based on the nature of different industries.
If you are in the manufacturing sector, you could explore topics such as employees' welfare, the effectiveness of preventive measures adopted in the factory regarding work accidents, and the effectiveness of industrial relation policies within the organization.
For an insurance company, you might consider looking into the motivation levels of employees and financial advisors, the effectiveness of training programs, reasons for agents' turnover, and competency mapping in relation to sales managers' input and output.
In the IT/BPO industry, topics like stress management, attrition levels, compensation plans, knowledge management, and analyzing different personality traits of team leaders could be relevant.
Additionally, there are some general topics to consider such as absenteeism, job satisfaction, the effectiveness of the recruitment policy within the organization, and performance appraisals.
I hope this helps you in your research. Let me know if you need further assistance.
