Objective: To determine whether employed family caregiver reports of caregiving to work conflict (CWC) are associated with emotional, physical, and financial strain, and whether organizational factors, including supervisor disclosure and caregiver-friendly workplace policies, attenuate these effects. Method: We examined 369 full-time employed caregivers of adults aged 50 years and above from the 2015 AARP and National Alliance for Caregiving population-based study, Caregiving in the United States, using ordinary least squares hierarchical regression and moderation analyses. Results: Regression analyses showed that caregiver reports of more CWC, in addition to disclosure of caregiving, were associated with greater emotional, physical, and financial strain after controlling for demographics and caregiving stressors, and workplace policies did not attenuate strain. Neither disclosure nor policies moderated the impact of CWC on caregiver strain. Discussion: Results suggest the importance of workplace strain in the caregiving stress process and suggest that disclosing caregiving responsibilities to supervisors should be closely examined.
