Lots of people have businesses on the side, and some places cater to these part-time/ small-time entrepreneurs with office sharing setups that may even involve support staff, like secretaries. But why couldn’t regular businesses cash in, too, leasing out their space, complete with computers and other equipment, on weekends and at night — when the regular employees are off? Why shouldn’t a newspaper, for example, let freelancers use the offices to write for anyone … in return for cash or reduced prices on stories? Just need a way to ensure phone calls get properly charged.
