Forty-nine percent of employees say they plan to do some holiday shopping online in the office, which is similar to last year's figure, according to a new survey by jobsite CareerBuilder.

As Christmas nears, shopping in the workplace becomes more popular, the survey finds, as 30 percent of respondents report that they are most likely to shop from work once Dec. 7 hits. While 43 percent of female respondents say they plan to shop online at work, 36 percent of male respondents say the same.

"Employers tend to be more lenient when it comes to workers using breaks or down time to get online and — in some cases — take care of some online shopping," says Rosemary Haefner, vice president of human resources at CareerBuilder. "However, it is the employee's responsibility to know and adhere to their company's policy regarding Internet usage. Be aware of how you spend time on the Web, and don't let your holiday shopping get in the way of your productivity."
