Methodology: 

To identify the most hated companies in America, 24/7 Wall St. reviewed a variety of metrics on customer service, employee satisfaction, brand value, and financial performance. We considered consumer surveys from several sources, including the American Customer Satisfaction Index (ACSI), as well as large declines in a brand’s value from sources like BrandZ and Interbrand. Employee satisfaction is based on worker opinion scores on workplace review site Glassdoor — this is not a Glassdoor commissioned report. We also accounted for current events that have impacted the public’s perception of the companies.
