More and more enterprises begin to adopt open and shared office space design, and one of the key problems caused by open and shared office space design is the lack of privacy. Based on the affective event theory, it has conducted a two-stage questionnaire survey of 210 employees with a two-week interval to explore how the lack of privacy in the workplace affects employees' work disengagement behavior through negative emotions. Finally, It was found that the lack of privacy in the workplace has a significant positive impact on employees' work disengagement behavior, and negative emotions play a partial mediating role between the two. In addition, the control point moderated the relationship between workplace privacy deficit and negative emotion: compared with the internal control point individual, the external control point individuals were more likely to be negatively affected by the lack of privacy in the workplace, and their negative emotions increased more obviously, and the impact on work disengagement behavior was also stronger.
