The social networking company's ranking dropped from No. 1 for 2018 to No. 7 for 2019, according to Glassdoor's list of 100 best places to work in the USA, which is determined by employee feedback.
A Facebook employee at the company's Menlo Park headquarters warned Glassdoor visitors not to believe all the negative press. The top tech company in the list is little-known Zoom Video Communications at No 2.
Glassdoor relies on anonymous employee reviews for its rating system. Companies are required to have at least 1,000 employees and 75 company reviews on Glassdoor, which uses an algorithm to calculate the rankings that assesses the quantity, quality and consistency of Glassdoor-approved company reviews shared by employees between October 23, 2017 and October 21, 2018. Workers said the company offers great training and opportunities to advance.
The firm ranked second on last year's list.
The company, although headquartered in Boston, has more than 90 locations in 50 countries. About 16,000 employees work for the firm.
"Glassdoor Best Places to Work winners are strategically investing in company culture, career growth opportunities and more, which also serves as a major recruiting advantage".
Facebook, which was No. 1 previous year, dropped to No. 7 for 2019, going from a 4.6 rating to a 4.5 rating among US -based employees. But Amazon doesn't find a space in the Top 100, which is rather surprising for a company that is one of the biggest in the history in terms of market capitalisation.
Facebook has suffered a recent string of high-profile missteps, pertaining to data privacy and potential biases. The search giant's ranking is also down from fifth place in 2018.
Bain & Company, Google and Apple are the only three companies to have made the list every year.
Google CEO Sundar Pichai was scheduled to testify before lawmakers on Wednesday, but the hearing is postponed due to the funeral for former President George H.W. Bush.
Athletic apparel company Lululemon ranked ninth, with an employee rating of 4.4.
"Work-life balance is awful", one employee wrote in a review. The company's overall score dropped from 4.6 to 4.5 out of five, marking the first time Facebook's score has declined since 2015, CNBC reports. These controversies started with the Cambridge Analytica revelations early this year but since then nearly every month there was something new.
