NEW YORK (BLOOMBERG) - It's not easy to keep all your employees happy, but these chief executive officers seem to have figured it out.

The CEOs of Bain & Company, Ultimate Software Group, McKinsey & Company, Facebook, and LinkedIn took the top five spots a just-released list of the highest-rated CEOs in the US.

According to a report from career website Glassdoor, each of the CEOs had an employee approval rating of 97 per cent or higher.

Last year, Google's Larry Page took the top spot and women were absent from the top 50. This year, four women made the list.

The highest-rated female chief executive was In-N-Out Burger's Lynsi Snyder at No. 17. Staffmark's Lesa Francis, Enterprise Holdings' Pamela Nicholson, and Deloitte's Cathy Engelbert also made the top 50.

Other well-known CEOs making their first appearance on the list include Nestlé Purina PetCare's Joseph Sivewright at No 9, NBCUniversal's Stephen Burke at No 39, and lululemon's Laurent Potdevinat in 48th place.

With a lot of uncertainty about the future at Yahoo!, CEO Marissa Meyer received a mere 64 per cent approval rating.

The report is based solely on the input of employees who anonymously and voluntarily provide feedback through Glassdoor, and the CEOs are then ranked according to their overall approval rating from the past year.
