But these Fortune 500 CEOs have managed to shake off the negative from their reputation, and garner near universal acclaim from their employees.

Using data from the 2016 Fortune 500 and Glassdoor’s Employees’ Choice Awards: Highest Rated CEOs, Fortune has compiled a list of the 13 CEOs on the Fortune 500 who have gained a massive amount of support and approval from their workforce.

Five of 13 CEOs lead companies in the tech industry, and more than half of the CEOs, seven, run companies in the Fortune 100. The rest come from a mix of finance, consumer goods, pharmaceuticals, and retail companies.

Here are some major data points from the list:

• The four CEOs best regarded by their employees hail from Silicon Valley tech giants such as Facebook, Salesforce, Google (Alphabet), and Apple.
• The 13 CEOs are also generally more well paid than their peers. The median pay of the CEOs, $15.8 million, is considerably higher than the median pay of CEOs on the S&P 500, $10.8 million, according to data from Equilar and the Associated Press.
• Four companies on the list were also among the 100 Best Companies to Work For: Goldman Sachs(No. 51), Salesforce (No. 23), Stryker (No.21), and Google(No. 1).
• Salesforce jumped 97 places on the Fortune 500, the ninth most extreme skip forward this year.
• Expedia CEO Dara Khosrowshahi’s pay rose 881% in 2015—likely making him the highest earning CEO in 2015 among all S&P 500 chief executives.
• Facebook CEO Mark Zuckerberg is the youngest chief executive on the Fortune 500, at 32-years-old.
• Only three companies headed by these beloved CEOs saw sales fall from the year prior. Sales for Procter and Gamble fell 6.8%, and 5.7% for Johnson and Johnson. Revenue for Goldman Sachs also slipped 2.2% year over year. Profits for P&G, Johnson and Johnson, and Goldman Sachs fell by 39.6%, 5.6%, and 28.3% respectively.

Glassdoor’s methodology relied on the anonymous company reviews submitted by former, or current employees. Employees were asked to decide whether they approve, disapprove, or have no opinion of their CEO. Glassdoor then put the data through an algorithm which also weighs the employee’s employment status.
