The protracted COVID-19 pandemic repeatedly demonstrates the necessity of effective communication inside and outside organizations. However, a deficient comprehensive study of factors able to affect managerial communication limit further progress in the improvement of such business interactions. The research fills in the knowledge gap about the comparative influence of various factors on managerial communication and particularly the impact of individual and organizational characteristics of managers on communication. The paper aims to determine the significance of the relationships between managerial communication and age, genders, managerial levels, and industries in private companies from the energy, education, trade, service, extraction, construction, and production sectors. Within the organizational study, 224 subordinates from Kazakhstan firms reflected on their supervisors’ communications through a multivariate closed questionnaire. The obtained data was further processed and examined through correlation coefficients and dispersion analysis. The research results identified the considerable relationship between communication practices and managers’ age (R2=0.9637), managerial level (R2=0.9640), and industry (R2=0.9653). The study reveals the weak relationship between manager’s gender and communication practices (R2=0.1535): women insignificantly outperform men in this linking process. The research postulates that effectiveness of managerial communication considerably varies by managers’ age, managerial level, and industry, and insignificantly by gender. The paper lays the groundwork for gender-unbiased practices of human resource management and contributes to the idea of building diverse management teams.
