Reward is a broad construct that has been said to represent anything that an employee may value that an
employer is willing to offer in exchange for his or her contributions (Chiang and Birtch, 2008). The lack of rewards
will create an unpleasant environment, thus diminishing employees’ work efforts and may cause them to withdraw
from their jobs. For these reasons, rewards are increasingly important. The main objectives of rewards are to attract
and retain employees, to motivate employees to achieve high levels of performance, and to elicit and reinforce
desired behavior of the employees.
