Abstract. The aim of this paper is to examine the relationship
between dark triad personality and supervisor expediency. The
researchers further investigated if Islamic Work Ethics (IWE)
moderates the positive association between dark triad and supervisor
expediency; such that the relationship is weaker when IWE is high.
Theoretical framework developed in present study is based on two
theories i.e., trait theory and theory of planned behavior. The two
set data was collected from employees working in health sector
of Pakistan. Set one questionnaires were filled by employees on
supervisory positions, they rated their own personality traits and
belief in Islamic work ethics. Set two questionnaires were filled by
the immediate subordinates of supervisors who filled set one. They
were asked to rate supervisor’s expediency. Data was collected from
241 supervisors and 241 respective subordinates. Code was assigned
to keep the track of supervisors and their respective subordinates.
Confidentiality was ensured to avoid any bias. The research result revealed that Machiavellianism, narcissism and psychopathy positively
and significantly impacts supervisor expediency. IWE moderates
the positive association between Machiavellianism, narcissism and
supervisor expediency. However, the moderation result was found
insignificant in the case of Psychopathy and supervisor expediency.
Empirical evidences confirmed that dark triad of personality leads
to supervisor expediency. The theoretical model tested in the study
provides insight and empirical evidences in literature. Implications
for the managers and future research directions are also discussed.
