The premise of social capital is based on social relationships that facilitate cooperation and collective action for mutual benefits.
In health-care organisations specifically, social capital is positively correlated to risk management and quality of care, as well as improving employee well-being and satisfaction, which in turn improves productivity, staff turnover and overall performance outcomes.
Social capital is also central to quality improvement within teams.
It is important to note, therefore, that conflict in a team is not necessarily a bad thing. It is for leaders to establish a climate and community where conflict is safe to explore. It is only then that teams will create their best, most robust, solutions.
