Here's a silly question: which profession needs coffee the most?
Answer: all of them.
In any case, research must go on.
Dunkin' Donuts and CareerBuilder.com said workers in food preparation and the service industry have the greatest need for coffee.
The online survey of 4,152 U.S. workers found food preparation and service workers were the most likely to say their productivity would drop without coffee, followed by scientists, sales representatives, marketing/public relations workers, nurses, media workers, business executives, teachers, engineers and IT workers.
The survey, which was commissioned by Dunkin' Donuts and CareerBuilder.com in honor of National Coffee Day Sept. 29th, found 55 percent of respondents said they drink at least one cup of coffee per day and 63 percent of coffee drinkers tend to have two or more cups of java during the workday. The survey had a margin of error of 1.52 percentage points with a 95 percent probability.
