Being Time's Person of the Year is one thing, but how about receiving a near-perfect approval rating from your own employees?

According to Glassdoor.com's third annual Employees' Choice Awards, Facebook CEO Mark Zuckerberg received a 95 percent approval rating this year. Facebook was also named the number one place to work in 2011, based on reviews from Glassdoor.com, marking the social network's first appearance on its top 50 list.

Glassdoor.com, a job vault best known as a destination where job seekers can find anonymous salary information, created the ranking based on roughly 150,000 employee reviews culled over the last 12 months. The survey asked 20 questions ranging from employee morale to senior leadership.

Facebook, which ousted two-year favorite Southwest Airlines, received mostly glowing reviews from its 59 surveys. Employees loved the company's start-up energy and perks like free food, dry cleaning, and concerts.

Not all the feedback was good, however. A few reviewers complained of growing politics, big egos, excessive meetings, and poor management outside the products team. Others worried about burnout as the company grew in size and stature.

Google, meanwhile, fell from 14th place last year to 30th place this year. Apple climbed two notches to 20th. CEO Steve Jobs, however, received a 97 percent approval rating.

Other tech companies on the top-50 list include: Overstock.com (#9), Shutterfly (#14), NetApp (#15), Salesforce.com (#41), and Intel Corporation (#45).
