Many believe they need a cup of coffee to get up and going in the morning. Now, a new survey suggests that same cup of coffee could help determine a sense of productivity at work.

The survey, commissioned by Dunkin Donuts and CareerBuilder, found food preparation and service workers are among those who need coffee the most.

Among the results, 43 percent of those who drink coffee said they feel less productive without a cup a coffee. The findings are based on a survey of more than 4,100 workers across the U.S.

Those who need coffee to get through the workday the most are:

1. Food Preparation/Service Workers

2. Scientists

3. Sales Representatives

4. Marketing/Public Relations Professionals

5. Nurses (Nurse, Nurse Practitioner or Physician Assistant)

6. Editors/Writers/Media Workers

7. Business Executives

8. Teachers/Instructors (K-12)

9. Engineering Technicians/Support

10. IT Managers/Network Administrators

Other findings include how much coffee people drink a day:
Sixty-three percent drink two cups or more, 28 percent drink three cups or more.

The survey suggests younger workers believe coffee keeps them productive; about 62% of workers between the ages of 18 to 24 said they are less productive without coffee. For workers aged 25 to 34, 58 percent also think coffee makes them more productive.

For women, 47% claim they are less productive without coffee compared to 40% of men.

The survey also broke down the regions that feel more productive with their daily dose of coffee. The results: 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.

This Saturday is National Coffee Day.
