The work studied the relationship between the tough guy’s macho culture and business performance in Nigeria. Tough-guy macho culture is a prevalent organizational model that combines fast feedback, high risk, and a focus on the present, often prioritizing individualism over teamwork. Hierarchical leadership and cutthroat competition fuelled by this culture have led to unethical practices, long working hours, increased stress levels, and neglect of personal and family responsibilities. Moreover, it perpetuates gender stereotypes and discrimination, creating a glass ceiling for women in leadership positions while discouraging individuals who do not conform to traditional gender norms from actively participating and contributing. Organizations need to embrace inclusive leadership and adopt explicit diversity and inclusion policies to combat Tough Guy Macho Culture. Implementing diversity and sensitivity training programs is crucial to promoting a more inclusive environment. Prioritizing employee well-being is essential, and organizations can achieve this by offering flexible work arrangements, family-friendly policies, and supportive programs that promote a healthier work-life balance.

By directly addressing and transforming this culture, organizations can cultivate a more inclusive and supportive environment, which, in turn, enhances their reputation and appeal to top talent. Creating a workplace that values employee well-being and promotes a healthier work-life balance will undoubtedly contribute to the overall success and growth of the organization.
