According to Great Place to Work, the methodology for this recognition "focuses primarily on employee opinion (which accounts for 75% of the final score) and the evaluation of people management practices."

"The Best Places to Work maximize their human potential through effective leadership, meaningful values, and a deep relationship of trust among all employees, regardless of who they are or what they do," reads the organization's website.

Now, "when these dimensions are present, work environments benefit from innovation and financial growth for their people, the company, and the country."

"The survey analyzes the organizational environment and employee experience in the following dimensions: credibility, respect, impartiality, pride, and camaraderie, thus allowing the identification of strengths and opportunities for improvement, serving as the first step in creating and implementing an action plan," Great Place to Work further explains.
