"The primary employer is saying, `Wait, I'm paying you for the sharp, fresh, energetic you,"' says Tom Gimbel, president and founder of LaSalle Staffing in Chicago. "If you're burning yourself at both ends, it's going to show."

Still, the good done to the moonlighters can be great. Besides extra income, moonlighters enjoy variety, freedom and chance to do something new. They may also find their part-time jobs strengthen what they do full time.

Besides, "it's fun," Michel says. Not only do his part-time jobs offer a chance to network, stretch his professional skills and make more money, but they also give him the variety he wouldn't find just in a full-time job.

"It's a way of pulling from the spice cabinet" he says, "and offering a little variety throughout the day."

At one time, computers were expected largely to remove the need for paper copies of documents because they could be stored electronically. But for all the texts that are written, stored and sent electronically, a lot of them are still ending up on paper.

It is difficult to measure the quantity of paper used as a result of Internet-connected computers, although just about anyone who works in an office can tell you that when e-mail is introduced, the printers start working overtime. "I feel in my bones this revolution is causing more trees to be cut down," says Ted Smith of the Earth Village Organization.

Perhaps the best sign of how computer and Internet use pushes up demand for paper comes from the high-tech industry itself, which sees printing as one of its most promising new markets. Several Internet companies have been set up to help small businesses print quality documents from a computer. Earlier this week Hewlett-Packard Co. announced a plan to develop new technologies that will enable people to print even more so they can get a hard copy of a business document, a medical record or just a one-line e-mail, even if they are nowhere near a computer. As the company sees it, the more use of the Internet the greater demand for printers.
