Who Drinks The Most Coffee In The Workplace?

Does your office practically run on coffee? It just might if you work in food service, science labs, or sales offices. 

In honor of the upcoming National Coffee Day this week, Dunkin' Donuts and Careerbuilder paired up to survey American workers to figure out which professions drank the most coffee. The survey questioned more than 4,000 workers for three weeks between August and September, according to a release. 

The findings? Better tip your food-service workers so they can keep up with their caffeine habit, as they rank number one in the survey. Scientists, sales reps, nurses, and teachers all cracked the top 10; as well as public relations/marketing execs and reporters and writers. (Judging by the number of Starbucks cups in our collective trash can, we'd have to agree.) 

Other stats from the survey: 63 percent of all coffee drinkers drink two or more cups per day, with 28 percent drinking three or more per day. Employees in the Northwest drink more coffee than those in the South or Midwest. And unsurprisingly, nearly everyone says that coffee helps their productivity.
