This interview with Sodexo CEO, Michel Landel, focuses on an in-depth study on the effects of gender balance in the work place.  As the 19th biggest employer in the world, Sodexo's 425,000-strong work force provided an extensive data pool.  

The study concluded that a gender-balanced work force, and specifically a gender-balanced management team was a great advantage to a business.  Sodexo found that achieving a "sweet spot" of 40-60% women leads not only to higher profits but also higher levels of customer satisfaction and employee engagement which all make for a more sustainable business model.  

What seems crucial here is not just having women in leadership positions, but having a good balance of men and women working to guide and lead a company.
