Abstract: In the context of digital intelligence, the boundaries between work and life are increasingly blurred, and employees need to flexibly switch roles and states in different fields and scenarios. To enhance employees' work vitality, some enterprises have used digital technology to creatively carry out the practice of non-working time cyber leisure across space and time. Although non-working time cyber leisure and its impact on employees' work and life have attracted attention from all walks of life, relevant academic results are not yet available due to the lack of clear conceptual definition and effective measurement tools. To fill this gap, this paper aims to clarify the connotation of non-working time cyber leisure, and based on grounded theory, constructs a measurement model that includes three dimensions: “social interaction communication”, “organizational value construction”, and “welfare system building”. Then, using a standard scale development process, a measurement scale for non-working time cyber leisure is developed. On this basis, based on conservation of resources theory, the positive impact of non-working time cyber leisure on employee thriving at work and the moderating role of trait mindfulness in the relationship between non-working time cyber leisure and mastery and control, problem-solving thinking and thriving at work are verified. This not only enriches the theoretical system of non-working time cyber leisure, but also provides a basis and suggestions for organizations to explore the management practices of non-working time cyber leisure.

Key words: non-working time cyber leisure, thriving at work, recovery experiences, problem-solving thinking, trait mindfulness
