Despite the growing body of literature on technostress, there is limited knowledge about the emergence of technostress among people working with physical robots. In this paper, we aim to address this research gap by exploring how technostress emerges among employees working with physical robots. The study was based on qualitative online questionnaire responses from 199 present or previous users of robots at work. Based on our data, we identified several robot-related environmental conditions that contributed to perceived work-related stress. In addition, we identified personal and situational factors that influenced perceived stress. Our findings reveal that the emergence of technostress among employees working with physical robots has distinct characteristics, and that the technostressors identified in previous studies are insufficient for explaining stress in this context. Therefore, our study extends the technostress literature and provides insights into employees’ experiences in organizations that use physical robots.
