The hottest place to take college courses these days is at Starbucks.

A growing number of Fortune 500 companies are offering their own, free college-level classes for employees, like Starbucks, Walmart, and even Jiffy Lube. 

And while you won’t earn a “Starbucks U” diploma, most of the courses can be applied toward an associate or bachelor degree at thousands of private and public universities.

For example, Starbucks offers management courses like “Barista Basics.” 

McDonald's Hamburger University has business and leadership classes. 

And Walmart offers time management and office management programs.

So, why are so many companies turning into mini colleges? It’s a smart business move. The courses boost the quality of their workforce, and makes employees more valuable and knowledgeable. 

Meanwhile, workers taking classes are more likely to be dedicated and work harder. Because they don’t want to lose out on the free education perk.
