The present article examines the impact of human resource activities on the perceived job productivity of teleworkers. Analyzing the data from a survey among 217 Teleworkers in the Ministry of Cooperation, Labour and Social Welfare shows that various activities of human resources in accordance with telework arrangements have significantly improved the job productivity of teleworkers. Results of testing the hypotheses by structural equation modeling indicate that voluntary selection, job involvement, output-based control, electronic monitoring, variable pay and social protection have a positive impact on the job productivity of teleworkers. However, the research data do not confirm the influence of cooperative learning and behavioral training. Based on these findings, the paper emphasizes that managerial contingencies in the field of human resources are critical and in this way policy makers and practitioners should consider them for the successful implementation of telework arrangements
