Nearly half of those surveyed left their office during the day to take care of personal errands, including going to the bank, picking up a gift, shipping a package, getting a manicure or pedicure and picking or dropping off dry cleaning, the study by digital media firm Captivate Network revealed.
Nearly 70 per cent employees use their work computers for personal online activities, including taking care of banking and insurance needs, scheduling vacations, shopping, finding a new recipe and searching for a new job.
In the last two years, the number of employees in US who are running errands during the day has increased by 31 per cent, according to the study.
The research also found an 11 per cent increase since 2011 in the number of workers who report having a healthy work-life balance, despite a 30 per cent jump in the number of employees working more than nine hours a day.
"People seem to be getting more comfortable with putting in longer hours," said Scott Marden, research director at Captivate Network.
