volunteers have rights too you know

Ally Fogg is working into a lather about the rights of unpaid volunteers over at CiF.

Volunteers should be protected against unfair dismissal. Indeed, they should claim the same myriad protections offered to employees and service users against discrimination, harassment and exploitation.

Doesn't this fundamentally misunderstand the nature of voluntary work? Time and effort are freely given and can easily be withdrawn by the volunteer without any notice. To suggest that volunteers should have rights also suggests that there should be a contract between volunteer and organisation which would alter the relationship permanently.
