Published together with our partner, Fortune, the Best Workplaces in the Bay Area rankings are based on feedback from more than 227,000 employees at Great Place to Work–Certified™ organizations with locations in the San Francisco Bay Area. Employees completed our anonymous Trust Index© survey, answering questions about how frequently they experience the behaviors that create a great workplace, including, for example, management transparency, professional development opportunities, meaningful work, promotion equity, and the generosity of benefit programs. Results from the survey are highly reliable, having a 95% confidence level and a margin of error of 5% or less. Being awarded a place on this list indicates the company has distinguished itself from peers by creating a Great Place to Work For All™. Rankings reward organizations where not only the majority of their employees experience a great place to work, but these experiences are highly consistent, regardless of who people are or what they do in the organization. Scores take into account the complexity and size of the employee population. Companies are rewarded based on how much of their business is located in the Bay Area.
