Salary rise is not the prime factor for quit. Employees are known by the organization in which they work. They devote years to the organization and are emotionaaly attached most of the time. Quitting is not a day when we make merry out of it. It is like end of a relationship. The main reason is the behaviour and policy of the immediate managers and HR which forces us to quit. Dirty politics is played by the managers among the team. Managers consider team-mates as secondary. They take the entire praise from the management and pass the shortcommings to the teammates. But Senior management does not look into this very aspect.
Do one exercise. Attend a walk in of your organization without letting them know that you are one of the aspirant. you will realize the reality how HR behave with people. Most of the time HR team consist of young girls who don't even know how to behave.
It is very easy to point at the teammates but ever a senoir management guy has a word with the last end of the hierarchy chain.
