Fortune just rolled out their annual list of "Top 100 Best Companies to Work For." The business magazine teamed up with Great Place To Work to reach more than 230,000 employees across the United States, conducting a nationwide survey that rated workplaces, caliber of bosses, and the support each employee receives for personal and professional lives. Survey results were compared to other companies of similar size and structure to better gauge the overall quality of each company.
