Of the many I would suggest you think of Employee Engagement, it's one which most people would want solid in-puts.

You may ask the following questions yourself
1. What made you to enroll Phd programme
2. What are your areas of interest - list it
3. Select one area, where you think you are passionate to seek knowledge
Once this much is done, follow standard research methodology and finalize the problem/hypothesis
You may find the following useful
