With the development of information technology, it has become common for employees to use electronic devices to handle work affairs during non working hours (work connectivity behavior after-hours), and the reaction of employees to this behavior is still uncertain. Therefore, based on the theory of resource conservation, the impact of work connectivity behavior after-hours of employees on workplace deception behavior was explored. Through data analysis of 307 employees, it is found that work connectivity behavior after-hours has a positive impact on employee workplace deception behavior.Job burnout has a mediating effect between work connectivity behavior after-hours and employee workplace deception behavior.Organizational support has a negative moderating effect on the relationship between work connectivity behavior after-hours and job burnout. These conclusions not only expand the research field of employee workplace deceptive behavior, but also provide useful suggestions for organizations to suppress workplace deceptive behavior.
