For more information about Time Banking we recommend Edgar S. Cahn's book - No More Throw Away People:

"If we accept a market definition of work, there are a few minor omissions worth nothing. Work does not include: raising children, taking care of one's elder parents, keeping one's family functioning, being a good neighbor, or being a good citizen. So work includes everything - except family, community and democracy. Some of us think those things are rather important. If they can't be addressed as work within the market, it is clear we need a larger framework than that supplied by market." (page 41).
