Coworking is a growing movement of spaces and people, usually independent contractors, who have realized that working together makes for happier, more productive work lives, so they’re making it happen without the hierarchy. The spaces vary, but they’re generally membership-based and value-driven. People who belong tend to believe in collaboration, openness, accessibility, and sustainability. There are thousands of coworking spaces listed in the coworking Space Directory (a wiki collectively owned and updated). More than 450 of them participate in what they call a coworking visa program, where you can belong to a space in Iowa, for example, but spend a few days working at the one in Italy.
