There are countless factors that go into determining whether an employer is a good fit for you, and your own preferences and inclinations are the strongest indicators of whether you'll sink or swim.

But we'd be deeply remiss if we didn't point out that the employer also strongly influences the equation: how its treat its employees, how prominent it is in its respective industry, whether the CEO takes everyone out for pizza once a week.

These factors, like salary and work-life balance, can all be charted, and 24/7 Wall St. considered all of them while drafting this list of America's best companies to work for. These are the places where workers are happy to be working, and, if the statistics are to be believed, you would be, too. Interested?

Like other technology companies, LinkedIn has excellent perks and good, free food, but employees at the company also rave about good work-life balance and a confident, inspired leadership. In fact, 97% of reviewers have a high opinion of CEO Jeff Weiner, higher than all but a few other CEOs. However, LinkedIn is also proof no employer is perfect — the company recently agreed to pay $6 million to hundreds of employees for unpaid overtime, plus damages.
