<p>Recent research on a perceived culture of companionate love suggests that it can positively influence employees’ attitudes and behaviors. However, its effectiveness may differ depending on employees’ emotional needs. To clarify which employees are more or less likely to benefit from the perceived culture of companionate love, this study integrates conservation of resources theory and attachment theory to explore explanatory mechanisms and boundary conditions. We test the proposed hypotheses using a paired field study of 241 employees and their direct supervisors. Our findings show that the perceived culture of companionate love alleviates employees’ emotional exhaustion, which in turn enhances job performance and reduces employee turnover. Moreover, attachment anxiety intensifies the negative impact of the perceived culture of companionate love on emotional exhaustion, subsequently influencing job performance and employee turnover. Conversely, attachment avoidance weakens this negative impact and its downstream consequences for job performance and employee turnover. This study elucidates how the perceived culture of companionate love affects employees and identifies the types of employees who are more likely to benefit, offering theoretical insights and implications for research on companionate love culture, attachment, and employee turnover.</p>
