In terms of volunteers—so 11(4) is simply confirming that people who might be there in some sort of a volunteer capacity, the legislation will not provide to them, and the various bargaining rights and other things that are contained in the legislation will not apply to someone who, perhaps for a short period of time—you know, a student who has maybe come into have a look at a production for a few hours and get a bit of experience about how these things work and is sweeping the floor—won't need to get brought into the ambit of the legislation. So the meaning of the volunteer is simply the normal meaning of the word "volunteer", and that is there to ensure that we don't inadvertently bring in a group of people for whom there was never any intention to do so.
