In the globalized world, organizations face intense competition. Economic, political,
social, and technological changes in the world force organizations to adapt and improve
themselves all the time. Personnel are important resources for the success of an organization.
They need to be knowledgeable and skillful; they need to have good attitude and be
responsible for the organization; they need to be enthusiastic, change-resistant, able to work
with others, and happy at work. Happiness at work results in good attitude towards the
organization, which in turn leads to efficiency and organizational goals. This is the ultimate
benefit an organization could obtain (Tseng, 2009).
