Methodology for Best Workplaces for Women in 2020

To determine the Best Workplaces for Women, Fortune partnered with the people analytics firm Great Place to Work® to analyze anonymous survey feedback representing more than 4.7 million US employees.

Employees responded to over 60 survey questions describing the extent to which their organization creates a Great Place to Work For All™. Eighty-five percent of the ranking is based on what women themselves report about their workplace, and how fairly those experiences compare to men’s reports of the same workplaces. The survey measures the extent to which women report their organizations create a Great Place to Work For All™ — for example, whether people trust each other and employees are able to reach their full human potential, no matter who they are or what they do. Great Place to Work analyzes whether different identities women hold change their experience of the workplace. They analyze these patterns relative to each organization’s size, workforce make up, and what’s typical in their industry and region. Great Place to Work also consider employees’ daily experiences of innovation, the company’s values, and the effectiveness of their leaders, to ensure they’re consistently experienced, as well.

Fifteen percent of the remaining rank is based on how well represented women are in the workforce and throughout management, taking into account industry trends. To be considered, at a minimum, companies need to employ at least 50 women, at least 20% of their non-executive managers need to be female, and at least one of their executives needs to be female.

To ensure survey results truly represent all employees, Great Place to Work requires that Trust Index© survey results are accurate to a 95% confidence level with a 5% margin of error or better. Companies with 10 to 999 people are considered for the small and medium segment; companies with 1,000 or more employees are considered for the large category.

Some data was collected prior to the COVID-19 pandemic and will not fully reflect companies’ roles or responses to their people or communities in addressing the impact of the coronavirus.
