Workers aren't worried about making personal phone calls at work, but many are calling friends and family with their own cell phones instead of the company circuits.
A recent Maritz Poll found that 44 percent of American wireless subscribers use cell phones at work for personal calls.
"With companies cutting back on and monitoring employee telephone use, wireless subscribers are finding a way around the system," said Paul Pacholski, division vice president of the Maritz Telecom Research Group.
"In a sense, the old 'smoke break' is being replaced by the cell phone break."
Of the 803 people polled by Maritz Research, 53 percent of wireless subscribers said they used the cell phone at work for personal reasons.
