55 It may be thought that there is some awkwardness about the legislature's use of employer and employee in s 5(3) WPA Act to describe parties who have not yet entered into a contract of employment, but the intended meaning is, nevertheless, clear enough. Even more awkward is the use of employer and employee in s 7B of the IR Act. By its terms, an employer and an employee who are parties to a workplace agreement "are not, in relation to one another, within the definitions of 'employer' and 'employee' respectively in section 7(1)." There is no quality about a workplace agreement, as envisaged by the WPA Act, which would have the effect that the parties to the agreement would not be respectively an employer and an employee within the defined meaning of those terms in the WPA Act and in s 7(1) of the IR Act. Indeed, that is necessarily accepted by the WPA Act as s 5(1)(a) defines a WPA as an agreement between employers and employees, those terms being defined in s 3 primarily by adopting by reference the respective definitions in the IR Act. Thus, it cannot be the intention or effect of s 7B, as was submitted, that "employer" and "employee" when first used in that provision have meanings other than the defined meanings. It was submitted the common law meanings of the terms should be implied. Were that the case they could not be parties to a workplace agreement. Rather, in my view, it must be the intended operation of s 7B to except from the definitions of employer and employee, for the purposes of the IR Act, as it were by way of an express limitation or an artificial deeming, those who are parties to a workplace agreement which is in force, whilst leaving those parties as employer and employee within the defined meanings of those terms as those defined meanings have been adopted by reference in the WPA Act. Both s 7B and s 7C operate to effect this exception or deeming in cases "where any employer or employee are parties to a workplace agreement". Each section is concerned with the relationship between an individual employee and the employer.
