Consideration
28 The principles of construction applicable to enterprise agreements are not in dispute. They include:
It is necessary to discern the objective meaning of the words used in the enterprise agreement, bearing in mind the context in which they appear and the purpose they are intended to serve (Transport Workers' Union of Australia v Coles Supermarkets Australia Pty Ltd [2014] FCAFC 148; (2014) 245 IR 449 at [22], Amcor Limited v Construction Forestry Mining and Energy Union [2005] HCA 10; (2005) 222 CLR 241 at [66], [30]).
Enterprise agreements are solely creatures of statute, in the interpretation of which there is no scope for private law concepts of contract or equity (ACTEW Corporation Ltd v Pangallo [2002] FCAFC 325; (2002) 127 FCR 1 at [33]). It follows that it is doubtful whether terms may be implied into enterprise agreements (Australian Nursing and Midwifery Federation v Bupa Aged Care Australia Pty Ltd [2017] FCA 1246 at [500]).
Evidence of negotiations may be used to determine the "background facts", known to both parties, however such evidence may not be adduced if it goes only to intentions or expectations (Automotive, Food, Metals, Engineering, Printing and Kindred Industries Union v ALS Industrial Australia Pty Ltd [2015] FCAFC 123; (2015) 235 FCR 305 at [120]).
29 Upon examining cl 34.1 in light of these principles, I am not satisfied that it is a provision which can be "contravened" for the purposes of founding a breach of s 50 of the Act.
30 First, turning to the language of cl 34.1, it is plain that the word "may" in that clause means no more than "has permission to". In other words, cl 34.1 provides that HPS has permission to require an employee to work reasonable overtime. Certainly the word "may" does not mean "must" or "shall", such that HPS is obliged to require an employee or employees to work reasonable overtime. The use of the word "may" in respect of HPS can be juxtaposed with the statement that employees "shall" work such overtime "as required". The clause grants an entitlement to HPS to require employees to work reasonable overtime - the obligation is on employees to work such overtime as is reasonable by reference to cl 5.
31 Second, while the CFMEU places considerable reliance in its arguments on the intentions of the framers of the relevant enterprise agreement and the history of enterprise agreements between the parties, I am not persuaded that this history or HPS's desire for certainty in identifying "reasonable" overtime results in restriction being imposed on HPS. In closing submissions the CFMEU summarised the evidence of Mr Spillman as:
(1) During the course of negotiations for the 2007 Enterprise Agreement the representatives of HPS made it clear that under the proposed new arrangement it had the ability to require people to work reasonable overtime despite the phasing out of the factored overtime scheme, and the CFMEU accepted that position; and
(2) During the negotiations Mr Randall said words to the effect that "the company wanted some form of quantification of reasonable overtime in the enterprise agreement so as to achieve certainty, following the decision to phase out the factored overtime scheme", and in response to that request Mr Spillman suggested two hours per week or 104 hours per annum because that was the same number that had previously been worked by the operational staff under the factored overtime scheme.
32 The CFMEU submits that this evidence supports and is entirely consistent with the construction it advances. However in my view this is not the case. Mr Spillman's evidence is actually supportive of the construction contended by HPS, namely that the cl 34.1, together with cl 5, provides certainty to HPS by entitling it to require an employee to work reasonable overtime in the amount of 104 hours per annum. It is clear that cl 34.1 is for the benefit of HPS. In this regard I also consider of little moment the failure of HPS to call Mr Randall to give evidence in this proceeding.
33 The CFMEU drew an analogy between the present circumstances, and the relevant clause considered by the Full Court in National Tertiary Education v Latrobe University [2015] FCAFC 142; (2015) 254 IR 238. In that case the Full Court considered the following words in an enterprise agreement:
The University is committed to job security. Wherever possible redundancies are to be avoided and compulsory retrenchment used as a last resort…
34 In particular, the CFMEU relied on the observations of White J in Latrobe University at [108]-[110] to the effect that it is the very nature of enterprise agreements made pursuant to the Act that they are intended to establish binding obligations, and the clause in that case was expressed in the language of obligation as evidenced by the use of such terms as "are to be avoided and … used as a last resort".
35 In this case however, and particularly in light of the observations of the Full Court in Construction, Forestry, Mining and Energy Union v Hail Creek Coal Pty Ltd [2015] FCAFC 149 at [56]-[59], the Court should be cautious of accepting evidence of the alleged intentions of the parties in framing cl 34.1. Objectively, such evidence as is before the Court indicates that cl 34.1 was framed against a background where the factored overtime scheme had ceased and where 104 overtime hours was generally accepted by the parties as "reasonable" overtime. There is nothing to support the proposition that any other amount of overtime would, by reason of the terms of either cll 5 or 34.1, be unreasonable. Indeed, previous agreements provided for circumstances in which employees could work overtime additional to their factored overtime of 104 hours.
36 Further, I do not consider that it is either possible or appropriate to purport to substitute cl 34.1 for the clause considered by the Full Court in the Latrobe University case, and apply the reasoning of their Honours to the clause in dispute in this proceeding. The context and language of the two clauses are completely different. The Court in Latrobe University was satisfied that the relevant clause was framed in terms of obligation. This is not surprising given such terms as "are to be avoided", which is the language of obligation. I am not persuaded that this is the case in respect of cl 34.1. Further, while the CFMEU also urges the Court to avoid unnecessary focus on words such as "will", "shall" and "may", it is clearly necessary for the Court to examine the plain and ordinary language of cl 34.1 in discerning the objective meaning of the words used. To that extent the fact that the parties to the 2013 Enterprise Agreement agreed on the use of the word "may" in the context of cl 34.1 is important in identifying the entitlements and obligations conferred by that clause, and where such entitlements and obligations lie.
37 Finally, cl 34.1 does not provide that HPS "may not" require an employee to work overtime unless that overtime is reasonable. The submission of HPS that the CFMEU's reading of the clause turns the clause "on its head" is correct. It does not follow from the existence of a mere entitlement to require employees to work reasonable overtime that there is a prohibition on requiring employees to work overtime that is at variance with the relevant standard. Those two points do not logically nor necessarily correlate.
