Abstract:

The present study examined how leadership can influence the impact of
job demands on well-being by facilitating the development of known
moderators of this relationship, such as social support. Direct and
moderated relationships were proposed between job demands,
leader-member exchange (LMX), supervisor social support, psychological
well-being and emotional exhaustion. Data were collected from
high-skilled employees and managers in a manufacturing plant in the
People’s Republic of China. Surveys were administered in two waves,
allowing longitudinal relationships to be tested. As hypothesized,
high-quality LMX relationships facilitated supervisor social support.
Also as expected, supervisor social support had a direct positive
relationship with psychological well-being and a direct negative
relationship with emotional exhaustion. However, job demands were not
directly related to either psychological well-being or emotional
exhaustion. Further, supervisor social support did not moderate the
relationships between job demands and (a) well-being and (b) emotional
exhaustion. The hypotheses were not supported in longitudinal
analyses. Results of supplemental analyses suggested that supervisor
social support partially mediated the relationships between LMX and
(a) psychological well-being and (b) emotional exhaustion. Possible
explanations for the findings are presented, followed by implications
of the results, study limitations, and suggestions for future research
in this area.
