In cities all over the United States, workers spend several hours a day in cars crawling along in traffic to get to offices many miles from home. They experience stress, waste time, and pay a lot for gas, car maintenance, and parking. Once they get to work, they make their way through a maze of cubicles, each with its computer, phone, and file cabinet. Nancy Alley, human resources manager at TBWA Chiat/Day, doesn’t. She stays at home, talking with managers over the phone and faxing in paperwork. Instead of walking down the hall to chat with coworkers, she E-mails them. Nancy is a telecommuter, someone who works some or all of the time at home. Since 1990, the number of U. S. telecommuters has grown from 4.2 million to 9.2 million.
Highway congestion, the high cost of office space, federal clean-air laws, reduced work forces, and lifestyle needs -- all these factors contribute to the growth of telecommuting. What makes it possible is technology.
A. producing challenges.
B. producing counters.
C. producing results.
D. producing problems.
