Actually, quite the opposite. While many of the news reports focus on the Fortune 500-type companies, most telecommuting happens in smaller companies. Most employment in the US and many other countries is spread across a large number of small companies, and isn't concentrated in the biggest ones. Small companies can adopt innovations more quickly, are often under pressure to cut costs or retain key people, and don't have to struggle with thick policy manuals and endless committee meetings before making changes like introducing telecommuting.
