WWOOFing is defined in the convention against illegal work as "solidarity and active holidays", it is an unpaid activity in agricultural areas. This is not work but an exchange, an act of solidarity, a discovery... There are no obligations of productivity, no subordination nor hierarchy, and no pay. The WWOOFer is there to discover, learn and voluntarily and freely participate at a host that wants to share his universe. Note that the MSA and WWOOF France have finally agreed on a common definition of WWOOF (in French).
