For the many Americans who enter the workforce each year, few decisions are as consequential as choosing a career. Picking a profession is only the first step, however. The next is deciding which company or organization to work for.

Based on 49 million reviews posted to Glassdoor, an online platform where employees can rate their employers, the average company rating is 3.4 out of 5. While a score above a 4 is relatively rare, there are a handful of major companies that appear to prioritize employee satisfaction — and the proof is in the feedback. There are 17 highly reviewed companies with a score of at least 4.3.

24/7 Wall St. used Glassdoor data to identify the best companies to work for. This is not a Glassdoor commissioned report. We considered only large, U.S.-based companies and excluded government agencies and nonprofits from our analysis.

In a written exchange with 24/7 Wall St., Glassdoor career trends expert Amelia Green-Vamos laid out some of what these companies are doing to keep their employees happy. “Trust in senior leadership is a leading factor underlying long-term employee satisfaction along with culture and values, and career opportunities.” To be sure, employee-submitted reviews for companies on this list frequently cite those same factors. These qualities are notably absent in many reviews for the worst companies to work for.

Compensation also appears to play a role. Average salaries for common positions in many companies on this list regularly extend into the six-figure range. It is likely no coincidence that several of these companies also rank among America’s highest paying companies.

When it comes to intangible assets of a company, employee satisfaction is critically important, but it is not everything. Despite a dedicated and happy workforce, one company on this list also ranks among the 10 companies with the worst reputations.
