On every continent, reaching gender balance remains an unmet goal. Despite progress during the last 50 years, women and men continue to experience unequal opportunities, particularly in employment, politics, leadership and economic empowerment. Women are disempowered relative to men in all 162 countries measured by the UN Gender Inequality Index. This year, the predicted time to close the global gender gap increased from 99.5 years to 135.6 years, according to the Global Gender Gap Report 2021 from the World Economic Forum. Aside from the moral imperative to strive for gender balance, there are also broader implications for business to consider. The leaky pipeline of female talent in conjunction with the war for talent mean that organisations must recruit, retain and leverage both men and women to perform at their best. Further, teams with gender balance tend to outperform all-male or all-female teams on challenging tasks, as gender balance enables diverse views and increases collective intelligence. Given the current needs for innovation and agility during the post-pandemic recovery, gender inclusion simply makes sense. Insead, a leading international graduate business school, has both a vision and a responsibility for achieving gender balance. To drive meaningful change, we must set an ambitious agenda and rally men and women to achieve it. To that end, Insead recently joined the UN HeForShe Alliance. It is comprised of leaders from business, non-profits and academia who are committed to achieving gender balance in their companies, communities and countries. There is a practical reason for making allyship central to this initiative. Men remain disproportionately in power across both business and government, accounting for around 90 per cent of all heads of state and Fortune 500 chief executives. For gender balance to become a reality, we need these leaders to contribute to making it happen. As pledged to the HeForShe Alliance, we will pursue five goals that build on the work of the Insead Gender Initiative. Our senior-level male allies, including the chairman and deans, will work with our women leaders to achieve a gender-balanced board by 2023. We will achieve equal representation of men and women on our board while also representing at least 12 nationalities and four continents. We will also reach at least 40 per cent female participation in the MBA programme by 2025. We will continue to work towards parity while representing a minimum of 65 nationalities in each cohort. However, reaching parity may take time, as we recruit from some countries with substantial gender gaps in education and employment. There are also plans to target 50 per cent female students in our Master in Management programme. In addition to achieving parity, we are committed to creating cohorts that represent a minimum of 35 nationalities. We will also hire 50 per cent women faculty during the next three years. We began making progress towards this goal before the pandemic; of the 12 faculty members in the last hired cohort, half were women. Finally, we will expand research on gender issues. We will continue our leading-edge work with global industry and academic partners to identify and test effective interventions, and share these with our students, executive participants, alumni and business partners. To enable the power of allyship, we must understand the role of male allies. Allies are not heroes rescuing women. Instead, they engage in an iterative process of investigating potential systemic biases, learning from those findings and advocating for change. They think like detectives and act like scientists – observing, challenging assumptions, asking questions, examining data and testing hypotheses. For example, if a male ally hears someone say that a woman is unfit for a role, they challenge the root of that assumption. After learning and understanding these dynamics, allies take action to advocate for fairer systems. These interventions may be small and opportunistic; for example, an ally might point out when a female colleague is interrupted in a meeting and invite her to finish sharing her idea. Other interventions may be more systematic. For instance, 10 years ago, we created an initiative at Insead to develop all our faculty as educators. This initiative benefits men and women – as professors and students – and has dramatically improved the quality of experience for women teaching. A recent analysis showed that student nominations for entry-level female professors for teaching awards increased 700 per cent since this programme was fully instituted. Sponsorship is also essential for correcting the imbalance of power between men and women. Not to be confused with mentorship, sponsorship involves advocating for a woman that is capable and deserving of a promotion. It also involves highlighting a woman’s talents and strengths to the decision makers involved in the promotion decision. These interventions enable more women to overcome systemic barriers to professional advancement. Finally, changing norms is key to reaching parity. In 1959, when Insead first opened its doors, women were not permitted to attend the MBA programme, as per the norm at the time. This norm has, of course, changed in the succeeding years. However, women remain a minority in our student population and still face barriers to reaching top leadership levels for maximum impact in their careers. We must achieve a critical mass of women, across business schools and boardrooms, to change these norms and overcome the marginalisation that women continue to experience. The overarching goal of this work is not to tear men down, or to give women advantages that create disadvantages for men. The ambition is to build a system that is fair and inclusive, and from which gender balance naturally emerges. Moving in this direction isn’t just good for women. It benefits everyone. <i>Zoe Kinias is an associate professor of Organisational Behaviour at Insead and the academic director of Insead's gender initiative</i> <i>Ilian Mihov is dean and professor of Economics and the Rausing Chaired Professor of Economic and Business Transformation at Insead</i> A version of this article first appeared in Insead Knowledge
