Life inside the 'Plex is pretty good. 

Every year,, an employer reviews site, publishes a list of "The 50 Best Places to Work." This year's list, released today, shows Google for the first time coming in at No. 1, jumping up from last year's No. 8 spot. Consulting firm Bain & Company, last year's top employer, took the No. 2 spot, with Nestlé Purina rounding out the top three.

"Google has always had a reputation for being great employer," Glassdoor career trends analyst Scott Dobroski tells Inc. "It's made our list every year, but it has never cracked the top three until now."

To compile the list, Glassdoor uses a proprietary algorithm that takes into account all of the company reviews submitted anonymously by current and former employees over the past year. Glassdoor's data science team then assigns each employer a ranking based on the quantity, quality, and consistency of reviews. 

According to Glassdoor reviews, Google's recently adopted paternity leave policy played an important role in the tech giant taking the top spot. (For more insight on why Google employees gave their employer rave reviews on Glassdoor, read "5 Reasons Googlers Love Where They Work.")

One subtle factor that plays an important part in how employees feel about their company is transparency at the highest level of the organization, particularly during difficult transitions. Dobroski cites this as one of the reasons both Ford (No. 35) and Toyota (No. 37) managed to nab solid spots on the list. In the last two years, both automakers appointed new CEOs.

When mishandled, however, a changing of the guard may result in employees losing trust in top-level management. That could be why Twitter, which was ranked the second-best place to work last year, is noticeably absent from this year's Glassdoor list. 

In June, former Twitter COO Ali Rowghani abruptly resigned. In July, the company brought onboard a new, accident-prone CFO, Anthony Noto. Since then, Twitter employees have witnessed the departure of other high-profile executives, including the VP of engineering, the VP of media, and a senior manager leading the analytics team.

"Twitter is an interesting case," Dobroski says. "It's still a great employer, but they've lost a lot of senior leadership recently, and that's impacted their employee satisfaction." 

Another reason Twitter failed to make the list is that morale is starting to come down from cloud nine after a "euphoric post-IPO high," Dobroski says.

"We saw this happen to Facebook too after their IPO," he adds. "They are losing that startup feel."
