See Fair Work Act 2009 s.172(1)
The Fair Work Act sets out matters which are permitted to be included in an enterprise agreement.
A term of an enterprise agreement has no effect to the extent that it is not a term about a permitted matter. However, the inclusion of such a term in an enterprise agreement does not prevent the Fair Work Commission from approving the agreement as an enterprise agreement.
The following matters are permitted matters:
- matters pertaining to the employer–employee relationship
- matters pertaining to the employer–union relationship
- terms about deductions from wages, and
- terms about how the agreement will operate.
