To determine America’s best companies to work for, 24/7 Wall St. independently reviewed employee ratings and testimonials on employee review site Glassdoor retrieved on June 5, 2019 – this is not a Glassdoor.com commissioned report. Glassdoor measures employee satisfaction on a scale of 1 to 5, where 1 is very dissatisfied and 5 is very satisfied. Only companies with scores of 4.3 or higher made our list. In cases where two companies had the same score, the one with more reviews ranked better on our list, and for companies with the same score and same number of reviews, the share of employees who would recommend a job with the company to a friend broke the tie. Glassdoor ratings are based on current and former employee reviews and are calculated using a proprietary algorithm that favors more recent reviews.
To be considered, a company had to have a minimum of 1,300 reviews on Glassdoor and be currently operating and headquartered in the United States. We excluded government agencies as well as nonprofit companies from our analysis. We also excluded certain staffing agencies for which a significant portion of reviews was submitted by individuals who used that company’s services but did not work for it directly.
Employee totals are for the most recent fiscal year available and came from company documents, Securities and Exchange Commission filings. Employment information for private companies was often unavailable, and in those cases, we used employment estimates provided by Glassdoor.
