According to Murphy (1989), job performance can be defined as “the set of behaviours that are relevant
to the goals of the organization or the organizational unit in which a person works”. Therefore, the job
performance of an individual plays a vital role in an organization’s growth. This is because it highly
influences the overall firm’s performance and also functions as the key variable in work and
organizational psychology (Sonnentag and Frese, 2002; Zacher, 2009).
