Tim Cook is a well-liked CEO, at least according to employee ratings on Glassdoor, a website that allows employees of any company to post reviews, ratings, and other such metadata about the companies they work for.

The current rating of Apple CEO Tim Cook on the service is a high 94 percent, gathered from all the employees who have rated him on the service, a total of 724 as of this writing. While Glassdoor is an opt-in survey system, it is anonymous. If they hated the guy, they’d probably say so. Anonymity plus the internet is anything but overly polite.

Facebook CEO Mark Zuckerberg has replaced Tim Cook as the highest-rated CEO in tech, according to employee approval ratings on Glassdoor. Cook’s 97% approval rating from 2012 has dropped down to 93%, which takes him from first position all the way down to 18th. Zuckerberg now has an impressive 99% approval rating.

If you’re a regular visitor to Cult of Mac, you’ll already have some appreciation of how terrific Steve Jobs is. But do his employees share the same opinion of him as us fans?  Well, according to the employment reviews and rating site Glassdoor, 97% of them approved of him as CEO — making Steve one of the most successful CEOs among those rated on the site.
