(a) an agreement between an employer and an award/agreement free employee or a requirement made by an employer of an award/agreement free employee, that is expressly permitted by a provision of this Part; or
(b) an agreement between an employer and an award/agreement free employee that is expressly permitted by regulations made for the purpose of section 129.
Note 1: In determining what matters are permitted to be agreed or required under paragraph (a), any regulations made for the purpose of section 129 that expressly prohibit certain agreements or requirements must be taken into account.
