The survey also reveals that coffee plays a major role in helping workers perk up on the job—43% of those who drink coffee claim they are less productive without it.
According to the survey, the workers that need coffee to get through the workday most are:
- Food preparation/service workers;
- Sales representatives;
- Marketing/public relations professionals;
- Nurses (nurse, nurse practitioner or physician assistant);
- Editors/writers/media workers;
- Business executives;
- Teachers/instructors (K-12);
- Engineering technicians/support; and
- IT managers/network administrators.
The majority of coffee drinkers do not stop after one cup, either—63% of workers who drink coffee drink two or more cups each workday; 28% drink three or more.
Comparing age groups, a greater number of younger workers indicate they need coffee for energy and motivation, as 62% of workers ages 18 to 24 say they are less productive without coffee and 58% ages 25 to 34 say the same.
While 55% of workers claim to drink at least one cup of coffee each workday, the Northeast holds the heaviest coffee drinkers, with 64% of workers drinking at least one cup per day, compared with the South (54%) and the Midwest and West (51%).
Coffee dependence seems to vary among genders, as well. Nearly half of female respondents (47%) claim they are less productive without it, compared with 40% of men.
The survey was conducted online by Harris Interactive on behalf of CareerBuilder among 4,152 U.S. workers (employed full time, not self-employed) ages 18 and over between August 13 and September 6, 2012.
