The most important point to keep in mind is employee exist becuase the company exists. If the company is not there, he cannot be there. Company is nothing but group of employees who drives it with a vision.
So the employee of any company
1. Must work for task he is taken for and
2. Must contribute to the growth of organization
Employee performance evaluation is on the work he supposed to do. But the rewards system is always for the contribution he does for org, team or group.
