In addition, the mediating influence of cultural intelligence in this relationship is also investigated. By focusing on 20 selected care homes in the healthcare sector of the United Kingdom, 346 employees were drawn from 84 work teams to participate in the study. Through the self-administered, structured, and close-ended survey questionnaire, research data were elicited from these respondents. From the descriptive analysis and simple mediation analysis conducted, while it was discovered that team members have an above-average level of observable and non-observable diverse characteristics, team diversity also has a positive impact on the performance outcomes of work teams. In addition, the positive influence of team diversity on team performance was found to be partially mediated by cultural intelligence. Thus, in light of these findings, recommendations were made for organizations particularly those in the healthcare sector to deploy more resources aimed at facilitating a more diversified workforce and also strive to make provision for those training programs in addition to human resource policies that promote employee cultural intelligence.
