An enriched nursing culture is the foundation of quality patient care, and as healthcare systems evolve, it becomes increasingly essential to foster a cohesive and inclusive environment in every aspect of employment practices.

By employing these approaches, health care systems can rebuild and strengthen their nursing culture, improving retention, onboarding, job satisfaction, teamwork, and enhancing the quality of care provided to patients. This article delves into practical strategies and application of SIT and inclusivity practices to restructure and revitalize nursing culture, emphasizing the positive impact on health care outcomes. An exemplar demonstrating the impact of the voice of the clinician in program development highlights the application of SIT and inclusivity to create culture. It concludes with leader practices for rebuilding nursing culture to include contingent labor as part of the care team.
