This study examined predictors of employee perceptions of organizational work-life support. Using organizational support theory and conservation of resources theory, we reasoned that workplace demands and resources shape employees' perceptions of work-life support through two mechanisms: signaling that the organization cares about their work-life balance and helping them develop and conserve resources needed to meet work and nonwork responsibilities. Consistent with our hypotheses, we found that higher demands (work hours and work overload) were associated with reduced perceptions that the organization was supportive of work-life integration. Resources (job security, fit between employees' needs and the flexible work options available to them, supervisor support and work group support) were positively associated with perceptions of organizational work-life support. The results of this study urge further scholarly attention to work-based demands and resources as predictors of perceived organizational work-life support and yield implications for managerial practice.
