What makes it so great?

"There is a [constant] sense of positivity and fairness," at 3M, says an employee. And it seems there's also a focus on healthy habits: Managers bring in fruit every week, and the company sponsors an employee "pedometer challenge" -- 10,000 steps per day -- to raise money for charity.

In Austria, the company keeps creativity alive with an Innovation Competition for employees, which boasts €500 cash awards and trips to the United States, London, and Berlin. "3M is the most ethical and transparent company that I've ever worked for," says the employee.
