59 The resolution of the question of construction posed by the competing submissions is not easy. The many provisions referred to in argument are not free from the 'apparent inconsistencies', if not 'illogicality', that often characterise collective agreements negotiated between employers and employees' organisations: cf City of Wanneroo v Australian Municipal, Administrative, Clerical and Services Union (2006) 153 IR 426, at 440 [57], per French J. The difficulties of construction are compounded by the fact that the AMOU Agreement does not specifically (let alone unambiguously) address whether or not SFC needs the prior agreement of AMOU to introduce crew based rosters.
60 Of course there is nothing unusual in an agreement, even one drafted with the benefit of considered legal advice, not specifically addressing an issue that turns out to be critical to the resolution of a dispute between the parties to the agreement. In this case, however, the omission of any explicit reference to SFC's ability (or inability) to introduce unilaterally crew based rosters is surprising. After all, the AMOU Agreement 2004 extolled the virtues of 'Vessel Teams' (an expression similar in meaning to 'crew based rosters') (cl 25.2). Moreover, I infer that SFC has been well aware for a considerable period of the safety benefits it says will flow from crew based rosters. Yet the AMOU Agreement apparently leaves the issue to be determined on the basis of inferences to be drawn from provisions not specifically concerned with the introduction of crew based rosters.
61 In order to evaluate the competing arguments it is necessary to consider the terms of the AMOU Agreement in the light of the surrounding circumstances and in the context of the Agreement as a whole. There are a number of matters that require careful consideration.
62 First, there is no dispute that under the AMOU Agreement 2004, SFC could have unilaterally introduced a crew based roster system in place of the system it had inherited. As I have noted, the virtues of 'Vessel Teams' were expressly identified in cl 25.2 of the AMOU Agreement 2004, which also recorded that '[SFC] and Officers [were] committed to working towards having self-managed work groups'. Apart from a notice provision, the only apparent qualifications to SFC's power as an employer unilaterally to introduce crew based rosters were the requirements that the changes:
· be for 'good and sufficient reason' (cl 44.1); and
· not be inconsistent with any other provisions of the AMOU Agreement 2004 (none of which appear to have imposed restrictions on the introduction of crew based rosters as such).
63 Secondly, despite apparently having the power to introduce crew based rosters during the currency of the AMOU Agreement 2004, SFC did not do so. The reasons for SFC's unwillingness or inability to introduce the rosters were not revealed by the evidence.
64 Thirdly, the fact that SFC had the unilateral power under the AMOU Agreement 2004 to impose crew based rosters on employees does not necessarily mean that a later collective agreement between the parties should be interpreted in the same way. It cannot be assumed, regardless of the language used in the AMOU Agreement, that it was drafted on the basis that SFC would retain pre-existing powers. There are many reasons (hypothetically speaking) why SFC might have chosen to relinquish any powers that it may have had. SFC might have realised, for example, that roster changes it imposed unilaterally would provoke serious industrial disputation and accepted that it was better to recognise the industrial realities.
65 Fourthly, as AMOU points out, the AMOU Agreement incorporates many references to 'new agreed … roster arrangements', 'new agreed rosters' and 'agreed rosters' (see cll 6.2.2.1, 6.2.2.4, 6.4.3, 7.1.2, 7.4.1, 8.1.1, 11.1). These expressions have no equivalent in the AMOU Agreement 2004. The language used by the parties cannot be ignored.
66 Fifthly, the AMOU Agreement expressly links the introduction of the new agreed hours of work and roster arrangements with the payment of the Annual Salary to employees in lieu of overtime entitlements. The parties record their commitment to working together to reach an early agreement on new rosters 'for the purpose of introducing' the Annual Salary (cl 7.1.1). Once the new arrangements are introduced, Maritime Officers receive the annual salary and lose their entitlement to overtime payments (cll 6.2.2.1, 11.1).
67 Sixthly, the AMOU Agreement does not expressly link the introduction of new agreed hours and rosters to the introduction of a crew based roster. In particular, neither cl 7 nor cl 8 expressly requires the new agreed rosters to incorporate a crew based arrangement. Clause 8 specifies certain principles with which the 'agreed rosters' must comply, but none necessarily involves a crew based roster. On the other hand, nothing in cl 8 is inconsistent with the introduction of crew based rosters should the parties choose to incorporate them in the new agreed rosters.
68 Seventhly, the AMOU Agreement records that the 'Parties are committed to developing team-based rosters' (cl 7.1.5). Clause 7.1.5 is one of five provisions included under the heading 'Rostering Consultation'. The first of these is cl 7.1.1, which commits the parties to work together to reach agreement on new rosters for the purpose of introducing the Annual Salary.
69 Eighthly, the AMOU Agreement records that SFC is committed to reviewing rosters on a regular basis and to meet with the Workplace Delegates Council to 'reach agreement on any proposed changes to the rosters' (cl 7.1.3). It is true, as SFC points out, that a provision in this form does not necessarily mean that agreement is required for any changes to be implemented. But, at the least, the provision is consistent with the parties assuming that the prior agreement of AMOU is required to change rosters that incorporate crew based arrangements.
70 Ninthly, the AMOU Agreement contemplates that the provisions set out in Annexure C will continue until the new rosters and the Annual Salary are put into operation (cl 7.1.2). The language used in cl 7.1.2 is somewhat opaque, if not confusing. For example, it is not correct to record, as cl 7.1.2 does, that the hours of work, rosters and overtime entitlements are set out in Annexure C. Further cl 7.1.2 says that the provisions set out in Annexure C, not the particular rosters then in force, continue to apply until the new agreed rosters and annual salaries come into operation. Moreover, although Annexure C replicates provisions found in the AMOU Agreement 2004, it does not replicate all the provisions. In particular, there is no equivalent in Annexure C to cl 44 (reproduced [25] above) and there is no reference to 'Vessel Teams' or any similar expression referring to crew based rosters.
71 Tenthly, both SFC and AMOU qualify the scope of their submissions by reference to what can fairly be described as pragmatic considerations. SFC accepts that the AMOU Agreement does not allow it to impose unilaterally any roster changes it sees fit. As I have explained ([44] above), Mr Dixon acknowledged in oral argument that any roster changes unilaterally imposed by SFC must be consistent with the provisions of Annexure C and that any proposed roster changes that are inconsistent require the agreement of AMOU. For its part, AMOU accepts that SFC can unilaterally impose some changes to the current roster system, provided that the changes do not alter the system itself. In other words, AMOU accepts that SFC can impose changes that affect only individual employees, rather than the system as a whole.
72 It seems to me that, having regard to the matters I have identified, the better construction of the AMOU Agreement is that SFC cannot introduce a crew based rostering system except with the prior agreement of AMOU. The AMOU Agreement does not expressly preserve or continue any pre-existing power SFC had under the AMOU Agreement 2004 to impose a crew based roster system unilaterally. Had the parties intended to preserve that power in SFC, they might have been expected to make some reference to their intention, either in the body of the Agreement or in Annexure C (which replicates some, but not all, of the provisions of the AMOU Agreement 2004). The omission of any reference in Annexure C to 'Vessel Teams' or crew based rosters seems to me significant, although not decisive, on the issue of construction I have identified.
73 As I have observed, cl 8 of the AMOU Agreement does not require the new agreed rosters to incorporate crew based rosters, but nor does it prevent such rosters being incorporated. The parties' ability to include or exclude crew based rosters in the agreed arrangements that trigger the Annual Salary does not, however, resolve the question of whether SFC is entitled to introduce crew based rosters without prior approval of AMOU. In my opinion, cll 7.1.3 and 7.1.5 are of particular significance on this question. They appear in the AMOU Agreement under the heading 'Rostering Consultation'. Clause 7.1.5, which has no equivalent in the AMOU Agreement 2004, states that the parties are committed to developing team-based rosters. This is an odd provision to include in the AMOU Agreement if the parties intended SFC to retain its power to require employees to work to crew based rosters regardless of the opposition of AMOU. The language of cl 7.1.5 suggests that the parties contemplated that they would work together to reach agreement on crew based rosters, whether or not the agreement would ultimately form part of the agreed rosters that would trigger the introduction of the Annual Salary.
74 Similarly, cl 7.1.3 commits SFC to review rosters on a regular basis and to meet with the Workplace Delegates Council to reach agreement on any changes to proposed rosters. The commitment referred to in this provision does not apply only to changes to the new agreed rosters, but to changes to existing rosters. This follows from the fact that cl 7.1.2, which immediately precedes cl 7.1.3, preserves in operation the provisions in Annexure C until new agreed rosters are put in operation. As I have explained, cl 7.1.3 does not mean that all changes to existing rosters, no matter how minor, must be agreed. But it tends to add some support to the conclusion that the introduction of crew based rosters requires AMOU's prior agreement.
75 SFC places particular reliance on cl 7.5 of the AMOU Agreement. In this respect, I think that SFC's submissions place a burden on the language used by the parties that the language cannot bear. The heading to cl 7.5 is 'Notification of Roster Changes'. It is a subsidiary provision, in the sense that it simply sets out the periods of notice required for particular categories of changes to rosters. Seven days notice must be given to Maritime Officers for an 'agreed change' and 21 days for 'a significant roster change'. It is difficult to see how a notice provision can shed light on the anterior question of whether AMOU's agreement is required for the introduction of crew based rosters.
76 It may be correct, as SFC contends, that 21 days notice under cl 7.5.3 is required for a unilaterally imposed 'significant roster change', but not for an agreed significant roster change. But this does not mean that cl 7.5.3 has no work to do. As Mr Dixon appeared to accept, SFC might well unilaterally impose roster changes on employees (not including the introduction of a crew based roster system) consistently with the provisions of Annexure C, the operation of which is preserved by cl 7.1.2. Some of these might be significant so far as the affected employees are concerned and thus require 21 days notice pursuant to cl 7.5.3. Indeed new agreed rosters, depending on their terms, might permit SFC to make further 'significant' roster changes without the agreement of AMOU. In that case, cl 7.5.3 would presumably specify the period of notice to be given to Maritime Officers of those changes.
77 For these reasons I think that the preferable construction of the AMOU Agreement is that SFC cannot introduce the crew based roster (or 'team-based rosters', as they are referred to in cl 7.1.5) without the prior agreement of AMOU. If such agreement is forthcoming, the crew based roster can be incorporated into the 'new agreed rosters' that trigger payment of the Annual Salary. Alternatively, they can be introduced independent of the arrangements that will result in the Annual Salary becoming payable to employees. But prior agreement by the AMOU to proposed crew based rosters is required.
78 It is unnecessary to decide the precise extent of SFC's power to alter unilaterally the current roster system. In particular, it is unnecessary to determine whether Mr Crawshaw's formulation of the limits of such a power ([50] above) is correct.
