U.S. workers admit to spending an average of about 2.5 hours to 5 hours per week on personal business while “at work.”

Researchers at a unit of CIGNA Corp., Philadelphia, have published that figure in a summary of results from a telephone survey of 1,149 part-time or full-time employed individuals 18 years of age or older who live in private households.

Only 46% of the participants said they were absent from work at least once in the past 6 months, but 61% said they had reported for duty while they were sick or coping with family and personal matters, the researchers report.

The participants who admitted to “presenteeism” said they did so an average of about 7 days in the past 6 months.

About 25% of the presenteeists said they went to work while distracted because they needed the money, but 38% said they went to work out of a sense of duty.
