The average cubicle farm, it seems, is where the 40-hour workweek went to die. According to a new survey, a staggering number of American professionals have workweeks that exceed 40 hours.

Virtual meetings software company PGi conducted an online survey of its customers that yielded more than 600 responses. Of those, 88 percent said they work more than 40 hours a week. Roughly a third each said they work between 41 and 45 hours, or between 46 and 50 hours.

Just over one in five said they work more than 50 hours a week. A main culprit in the lengthening of the workweek is technology that lets people work anywhere.

"I think a lot of it has to do with the "always on" atmosphere that's permeated across our culture," said PGi executive vice president of strategy and communications Sean O'Brien.

PGi found that 71 percent of survey respondents take home work on a weekly basis, with around 25 percent bringing work home four or more days each week. "I think, sometimes, the culture is led from the top," O'Brien said.
