Previous literature presents a gap to study the mediating mechanism in the
relationship between use of social media to perform a job and employees’
productivity. Based on the transactional stress and coping model, we
conducted the present research to assess the serial mediation of
information overload and ambiguity intolerance for this relationship. Using
adapted research questionnaires, we used an online data collection
technique to collect data from a sample of 232 employees working with
Pakistan International Airlines (PIA). Results obtained through structural
equation modeling, indicate significant serial mediation of information
overload and ambiguity intolerance in the relationship between use of
social media and overall employees’ productivity. We also found that use
of social media is positively related to information overload and ambiguity
intolerance and negatively related to employees’ overall productivity. The
study has contributed to the literature by identifying situational,
psychological, and behavioral consequences of use of social media at
work. Research has discussed several implications for organizations and
researchers.
