Facebook, Google and Apple have been voted among the top 10 best places to work. Company review site Glassdoor published the findings in their fourth annual Employees' Choice Awards.

The list is comprised of the top 50 best places to work based on feedback from over 250,000 employees. The study takes into account things like work-life balance, salary and benefits, advancement opportunities and even opinions of how the CEO runs the company.

Of the three, Facebook ranked the highest at 4.3 out of a possible 5, good for a third place finish. Employees at the social networking site admitted that the workload was heavy but rewarding at the same time. Workers are treated like real adults and given a lot of responsibility, but the perks are "unreal" and the atmosphere is fun. CEO Mark Zuckerberg scored an 89 percent approval rating based on 27 ratings from his employees.

Google earned a fifth place rating with a score of 4.0 overall. One reviewer posted a "day in the life" scenario that highlights many great perks including a free shuttle to work, free gourmet breakfast, a workout with a personal trainer in the gym before lunch, a $5 massage, gourmet dinner and a free shuttle ride back home. Of course, there's some work scattered in there too but considering those daily perks, it'd be easy to work at your highest level. CEO Larry Page earned a 92 percent approval rating based on 74 reviews.

Apple rounds out the top 10 at the number 10 spot. Apple employees in general praised the company for being able to "work on the products that people have real emotional commitment to", having a fun environment and great benefits and pay. Some of the negatives reported by Apple store employees include repetitive tasks and little room for advancement. CEO Tim Cook scored a 96 percent approval rating, the highest of the three tech companies highlighted in the top 10.
