Tim Cook is still well-loved by Apple (AAPL) employees — he’s just not as well-loved as he was a year ago. Glassdoor’s most recent CEO approval ratings show that 93% of Apple workers approve of the job Cook is doing, down from the 97% approval rating he had last year when he was ranked as the most popular CEO in the world. Cook now sits in the 18th slot. Taking his place atop Glassdoor’s list this year is Facebook (FB) CEO Mark Zuckerberg, who scored a 99% approval rating from employees to stand alone as the world’s most favored boss. Other popular tech CEOs on this year’s list include Qualcomm (QCOM) CEO Paul Jacobs, who ranked 8th among all CEOs with a 95% approval rating; Google (GOOG) CEO Larry Page, who ranked 11th with a 95% approval rating; and Amazon (AMZN) CEO Jeff Bezos, who ranked 16th with a 93% approval rating.
