PurposeThe study explored the relationship between the two concepts—internal communication satisfaction (ICS) and life satisfaction. Additionally, the study analyzed the link between eight internal communication dimensions (satisfaction with feedback, satisfaction with communication with immediate superior, satisfaction with horizontal communication, satisfaction with informal communication, satisfaction with information about the organization, satisfaction with communication climate, satisfaction with the quality of communication media and satisfaction with communication in meetings) and life satisfaction.Design/methodology/approachTo exclude the potential impact of contextual factors, we conducted a quantitative field research on a homogeneous sample of 507 respondents, employed in a multinational organization. For the assessment of ICS, we used the Internal Communication Satisfaction Scale (UPZIK), developed by Tkalac Vercic et al. (2009). For the assessment of life satisfaction, we used the satisfaction with life acale (SWLS) developed by Diener et al. (1985).FindingsResults showed a very high, statistically significant correlation between ICS and life satisfaction. All dimensions of ICS are highly correlated with life satisfaction, but this relationship proved to be the strongest between life satisfaction and two dimensions of ICS (satisfaction with informal communication and satisfaction with communication climate).Research limitations/implicationsOur study has three general limitations: (1) the dataset is of cross-sectional nature, which prevents inferring causality between variables; (2) a common source bias is present (ICS and life satisfaction are measured from the same source) and (3) we used self-reports [given the subjective nature and others’ reports of life satisfaction yield weaker but similar results (Erdogan et al., 2012)].Originality/valueWe identified satisfaction with internal communication, as a work domain that has not yet received attention in the management literature, to have an important role in life satisfaction. Among others, we found satisfaction with informal communication and satisfaction with communication climate to be especially relevant ICS dimensions, implying that organizations should primarily cultivate non-formalized dimensions of internal communication—a positive communication environment.
