It also examines how family involvement in ownership and management, along with the presence of family employees, moderates this relationship. Using a socioemotional wealth (SEW) perspective and structural equation modelling, data from 490 medium‐sized Spanish family firms were analyzed. The findings indicate that although formalized HR practices generally enhance firm performance, the effectiveness can be undermined by high levels of family involvement, particularly in ownership, as it may prioritize family‐centric goals over professional HR management. This study highlights the complex interplay between HR strategies, family dynamics and performance outcomes, emphasizing the need for strategic HR management that balances familial and organizational objectives in family businesses.engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/journal article1936-4490https://doi.org/10.1002/cjas.70021Digital Object Identifier (DOI)https://onlinelibrary.wiley.com/journal/19364490open accessM12M51M52M53M54Family firmsFirm performanceHuman resource formalizationHuman resource practicesSocioemotional wealthCiencias SocialesAdministración de empresas5311 Organización y Dirección de Empresas
