Non-family employees are indispensable resources for family firms as they grow. However, despite the recent scholarly attention toward non-family employees, it is still not clear how such important human resources should be managed and/or retained in family firms. To add to the limited body of knowledge on non-family employees working at family firms, this dissertation highlights the role of family-friendly workplace practices in preventing turnover intentions of non-family employees based on conservation of resources theory. Drawing on a sample of 116 dyad data (family business owner - non-family employee), this dissertation shows that family-friendly workplace practices prevent turnover intentions of non-family employees through decreased burnout. Moreover, it is found that family-friendly workplace practices in the family firms are affected by family influence. Thus, this dissertation not only creates avenues for future research on non-family employees, but also provides insight into the critical role of family-friendly workplace practices in the family firms.
