PurposeThe purpose of this paper is to analyse the impact of a leader’s communication style (LCS) on the quality of interpersonal exchanges between leaders and followers (LMX), and how this translates into the employee’s affective organizational commitment (AOC), in the context of Peru.Design/methodology/approachAn integrated model of six dimensions is used to measure LCS. Using multiple hierarchical regressions and the Preacher and Hayes mediation model, the study focuses on determining the direct and indirect effect of each of the dimensions on LMX and organizational commitment.FindingsThe dimension preciseness shows a significant direct association to AOC. Four dimensions are significantly related with LMX: expressiveness, preciseness and questioningness with a positive sign, while verbal aggressiveness records an important negative one. The same four dimensions show an indirect effect on AOC through LMX. Emotionality and impression manipulativeness do not record significant results.Research limitations/implicationsThe research was carried out with a sample of 253 white-collar Peruvian professionals with high-level studies and managerial experience, which are not necessarily representative of the labor population. This research provides comprehensive evidence on how leaders’ communicative behavior may contribute to desirable outcomes such as employee commitment in a Latin American cultural context, although the findings may apply to other cultures.Practical implicationsThis study contributes to clarify that each dimension of the LCS impacts differently on subordinate perceptions; leaders should understand this model and be able to make the necessary adjustments to their communication in order to obtain the desired results of leadership. The leader’s ability to communicate with a style characterized by expressiveness, precision, and questioning makes it easy to build high-quality LMX relationships for Peruvian employees. On the contrary, a communication style characterized by high levels of verbal aggressiveness may negatively affect subordinates, limiting the possibility of building high-quality LMX relationships. This, in turn, affects AOC of employees.Social implicationsThis study is a contribution to clarify that each feature of the LCS has a different impact on the perception of the subordinate, for which the leaders should be trained to understand this model and be able to make the necessary adjustments to obtain the desired results of leadership. The leader’s ability to communicate with a style characterized by expressiveness, precision and questioning makes it easy to build high-quality LMX relationships for Peruvian employees. On the contrary, a communication style characterized by high levels of verbal aggressiveness will negatively impact subordinates, limiting the possibility of building high-quality LMX relationships.Originality/valueThe value lies in revisiting the construct “leader’s communication style” to turn it into an instrument for the exercise of leadership. It is a contribution in favor of leaders becoming aware that their own communication style constitutes an instrument of effective leadership and a lever to optimize the commitment of their collaborators toward the organization.
