NEW YORK—I’m a virtual office worker and I’ll admit it ... I probably drink more coffee than most cubicle dwellers. But maybe I’m just the over-caffeinated exception.

So when I saw a survey in honor of National Coffee Day on Saturday, it caught my attention. Writing blog posts from my virtual office and drinking coffee go hand in hand.

Commissioned jointly by Dunkin’ Donuts and CareerBuilder, the survey reveals which workers are in professions that need coffee the most.

According to the survey, food preparation and service workers won out as the ones who need coffee the most, followed by scientists and sales representatives. Marketing and public relations professionals ranked fourth while nurses ranked fifth.

Editors, writers and media workers collectively ranked sixth. (That surprised me—I thought it would be higher.) Business execs ranked seventh, teachers ranked eighth. Rounding out the top 10, engineering technicians ranked ninth and IT managers/network administrators ranked last. Many of those professions can work from a virtual office.

Indeed, the survey reveals that coffee plays a major role in helping professionals perk up for work. Forty-three percent of workers who drink coffee claim they are less productive without it. Sixty-two percent of workers aged 18 to 24 say they are less productive without coffee, with 58 percent of workers aged 25 to 34 making the same claim. (I’m a little older than that, but I rank with the young ones.) Meanwhile, 47 percent of female workers claim they are less productive without coffee, compared to 40 percent of male workers.

Virtual offices can make you more productive, other studies show, but when you add coffee to the mix it’s an ideal combination. Users of virtual offices in New York can probably relate, especially being in a 24/7 city where workshifting is the name of the came for many. And speaking of New York, 64 percent of workers in the Northeast drink at least one cup per day, compared to the South at 54 percent and the Midwest and West at 51 percent.
