Which of the following is the best reward for an employee in your opinion?

As per my opinion satisfaction is the most important, if you are satisfied then you can deliver the best and you can get all the things, Bonus,PROMOTION etc

It depends on the employee. Rewards should not be mutually exclusive. In my opinion, for the majority of employees, a salary increase is the best reward. A smart company will not rely on a single reward system for its employees. Nor will it incentivate its employees with the same package of rewards. As the saying goes, "Different folks need different strokes."

let Him understand that business is incomplete without Him, Is the ultimate reward he could get ever.

Satisfaction includes most of the above.i will vote for career or job satisfaction.

it depends on an employee nature and a reward system in a company.

Maslow's hierarchy of needs Suggests that employees have different levels of motivation for rewards when it comes to Reward.

But above all, it is a ground reality that more than80% are becoming happy by Salary. There are very few who prefer satisfaction and other non cash benefits.
