Women are 65% of the employees who’ve been categorized as “high-potential” by this diversified health care benefits company, which means that they follow development plans that capitalize on their strengths and work with senior leaders to address gaps. Once they’re actually under consideration for top roles, they may also find themselves directing company projects, attending leadership conferences or tackling short-term assignments to sharpen their skills.
