More than half of people (50.7 percent) with Internet access at work plan to do some holiday shopping from the office this year, up from 44.7 percent last year, according to a survey by the National Retail Federation's Shop.org.

Younger employees with Internet access at work were most likely to say they planned to shop from the workplace, according to the survey. The survey found that 71.5 percent of respondents aged 18-24 years old and 66.4 percent of respondents aged 25-34 years old said they plan to browse or buy online from the office this holiday season.

Shop.org says that most workers who do their online holiday shopping at work do so during their lunch hours or before and after work.

"Online retailers typically see huge surges in website traffic during traditional lunch hours," said Scott Silverman, executive director of Shop.org.

The survey, which included 8,090 respondents, was conducted for Shop.org by BIGresearch from November 1-8, 2006.

Shop.org has coined the term "Cyber Monday" to describe the online shopping that takes place on the Monday after Thanksgiving. However, Cyber Monday isn't the biggest day of online shopping during the holiday season. In 2005, Cyber Monday ranked as the ninth most active online shopping day in terms of transactions processed, according to a report by MasterCard. The report found that the second Monday after Thanksgiving (December 5) was the most active online shopping day of the season last year.
