Sir, I am not running behind the salary or more money however I want to understand more about my role and responsibilities in your company. So, according to JD, you can decide in a better way to express the current scenarios of the position. Further, we all know about the market trends about salary of a good and reputed company. So, I think 30% hike should be the best one by which I don't need to think about compensation and further no need to find another job in future. Moreover, I will stick with your company in the long run.
