Pam Nicholson, president and CEO of Enterprise Holdings, has been named to Glassdoor’s Highest Rated CEO recognition list for 2016.

Glassdoor, a job and recruiting marketplace, released its annual report, highlighting the highest rated CEOs and recognizing top leaders throughout North America and parts of Europe.

“Inspiring and motivating an entire workforce is an overwhelming, yet imperative, undertaking,” said Robert Hohman, Glassdoor’s CEO and co-founder. “The CEOs on this list have earned the approval and respect of their employees, evidenced by the feedback shared on Glassdoor. This list celebrates that achievement and challenges all CEOs to aim to do the same.”

Among CEOs at large U.S. companies, Nicholson received a 94% percent approval rating based on anonymous and voluntary reviews that Enterprise Holdings employees shared on Glassdoor throughout the past year. She ranked No. 31 out of 50.

“Pam has been inspiring her teammates to succeed since she joined the company as a management trainee 34 years ago, so it’s no surprise that employees overwhelmingly appreciate her leadership and performance,” said Carolyn Eiseman, director of employer brand for Enterprise Holdings. “Social engagement is a critical component of our identity as an employer, and Pam’s recognition reaffirms the importance of connecting with current and future employees in the digital space.”

Nicholson also has been ranked as one of Fortune magazine’s Most Powerful Women in Business (MPW) for the past nine years.
