(1) A term of a collective agreement has no effect to the extent that it is a term about a matter other than a matter mentioned in subsection 536MK(2) or (3).
(2) A term of a collective agreement has no effect to the extent that it deals with matters that are primarily of a commercial nature that do not affect the terms and conditions of engagement of regulated workers covered by the agreement.
(3) However, if a collective agreement includes a term that has no effect because of subsection (1) or (2), the inclusion of the term does not prevent the agreement from being a collective agreement.
