As technology continues to change, electronic monitoring of work performance is experiencing another wave of interest from businesses and scientists. Based on the opinions of 100 warehouse employees, whose work is monitored using electronic tools, it was shown that the perceived impact of monitoring on increasing effectiveness and positive evaluation of the workplace are the best predictors for reducing dissatisfaction with monitoring, while the emotional cost and quality of one’s work do not affect this dissatisfaction. It was also shown that evaluation of the workplace is related to employees’ use of the opportunities offered by the monitoring tool, i.e., the use of help from superiors via monitoring. Several practical recommendations and directions for further research were formulated.
