After being rated one of the best places to work in the U.S. in 2014, Twitter's perception has taken a major hit.
The social media company has completely fallen off Glassdoor's annual Best Places to Work list, which ranks the Top 50 companies to work for in the U.S. Last year it was the top rated tech company, and the second best company overall.
"It's probably the single biggest change and surprise this year that Twitter didn't make the list at all," said Robert Hohman, co-founder and CEO of Glassdoor.
Hohman said that the company still ranks above average as a place to work,but it took a hit because a number of management changes in leadership during the last year.
Numerous positions, including its chief operating officer, chief financial officer and key executives in media and engineering, have all seen turnover in 2014.
