Proper construction of cl 12.4.1(c)
82Although the grounds of appeal contend that his Honour erred in construing the clause in various respects, ultimately the compass of the dispute between the parties was relatively narrow.
83The PSA accepts that the first of the declarations made by his Honour was not in the terms that it had sought, nor did it reflect what either party had contended for, in that it imposes a requirement for a 16 hour break in any rolling 24 hour period. The PSA concedes that the declaration is inconsistent with what it accepts involves no overtime entitlement, namely that a casual officer could work a particular shift (say an A (day) shift) commencing at any time between the range for that category of shift followed the next calendar day by that same category of shift without there being any entitlement to overtime under the Conditions Award (T 22.24). The PSA also concedes that the second declaration is otiose once the first is made.
84It was accepted by both parties that the particular class of work in this case is that relating to the provision of correctional services and that cl 12.4.1(c) relevantly directs attention to the daily roster pattern for non-casual (whether permanent or temporary) correctional officers. It was also accepted that the question as to what is the said "daily roster pattern" (at any particular time or from time to time) is a question of fact.
85As to the meaning of "day", CSNSW contends that his Honour erred in having reference to cl 3.12 of the Conditions Award (the definition of "daily rate" or "rate per day") and standard practice in the workforce when determining that the "daily" pattern was to be viewed over a 24 hour rolling period.
86The fundamental point of distinction between the parties is that CSNSW maintains that the "daily roster pattern" applicable when considering the entitlement of casual correctional officers to overtime under cl 12.4.1(c) is that which was established by Mr Thorsby's evidence and also taking into account cl 87.11 of the Conditions Award: namely, one eight hour shift per day in a B, A, C shift configuration commencing with the B shift. Where a B shift commences between 2200 hours and midnight, being before what would normally be regarded as the beginning of the calendar day, CSNSW maintains that the B shift is to be taken to commence on the next calendar day when determining the daily roster pattern.
87The PSA submits that the application of the Scheduling Principles results in a roster pattern, on any particular day, for non-casual employees and argues that the obvious intention of the Conditions Award is that casual employees are entitled to overtime if working in excess of that daily roster pattern, i.e., in excess of the manner in which non-casual employees would work.
88CSNSW maintains that, even if it is assumed that the rules set out in the Scheduling Principles for preparing the 28 day full time correctional officers' roster are applicable and, at any given time, have been correctly applied, those Scheduling Principles will not establish a "daily" roster pattern. In essence this is because reference to the work schedule principles in cl 2.1.3 of the Scheduling Principles necessarily requires focus on more than one calendar day (when applying the fifth and sixth principles for example).
89CSNSW appears to accept that, on any particular day, the application of the Scheduling Principles will reveal a pattern of shifts but says that, as between one calendar day and the next, there is no discernible pattern other than a requirement for an eight hour break between shifts. Its submission is that to impose the fifth, sixth and seventh principles set out in cl 2.1.3 of the Scheduling Principles is in effect to import a four-weekly roster pattern rather than a daily roster pattern when determining overtime entitlements for casual correctional officers.
90The practical difference between the two constructions emerged during the course of argument, as being: whether the "daily roster pattern" for the purposes set out in cl 12.4.1(c) requires that an A, E, D or C shift not precede a B shift and that a C shift not precede an E or A shift (i.e., the fifth and sixth principles) such that a casual correctional officer is entitled to overtime if required to work shifts contrary to that pattern.
91The PSA does not contend that overtime is payable if a casual correctional officer works a B shift followed as his or her next shift by another B shift (or an A shift following an earlier A shift) even if there are less than 16 hours between the two shifts due to differential starting times for the respective shifts. Its contention is that overtime is payable if an A (day) shift precedes a B (night) shift or a C (afternoon) shift precedes an A (day shift) even though those shifts fall on consecutive calendar days. It contends that the daily pattern includes that the employee would not, before they worked the B shift, have worked an A or C shift on a preceding day (T 39.39), the intention being that they be entitled to overtime if they work outside the arrangements that would apply to a non-casual employee doing the particular class of work that casual employee is engaged to perform.
92Thus the two scenarios where an entitlement to overtime is disputed are, first, where a C (afternoon) shift is worked on one calendar day and an A (day) shift is worked on the next calendar day, and, second, where an A (day) shift is worked on one calendar day followed by a B (night) shift (whether that B shift commenced at 2200 on that same calendar day or at midnight, i.e., on the commencement of the next calendar day).
93"Pattern" imports the notion of a design or structure. Clearly, the expression "daily roster pattern" requires that, when determining whether a casual employee is entitled to overtime on a particular occasion that he or she works, regard is to be had to what, at that time, is the "pattern" or configuration of the roster for non-casual correctional services officers looked at on a daily basis. What the roster is from day to day may of course differ (and there may be anomalies where officers swap particular shifts) but the expression "daily roster pattern" contemplates a "pattern" for the "daily" rostering of work by non-casual correctional officers.
94The evidence from which a conclusion can be drawn as to what, as a matter of fact, the daily roster pattern was for present purposes (i.e., at the time or over the period relevant to this dispute) includes not only Mr Thorsby's evidence as to the long-standing common practice for rostered shifts but also the Scheduling Principles.
95There might potentially be a different pattern for daily work depending on whether one looks at the daily work rosters over a week or a month or some other period, but what that issue really demonstrates is that when one looks for a pattern emerging from roster schedules that cover more than one day's work, a different pattern may be revealed by reference to how each day's shifts are structured by reference to what has happened the day before or what is rostered to happen the day after. This, in my opinion, is the force of CSNSW's complaint as to reliance on a 28 day roster.
96The PSA's argument, insofar as it focuses on the fifth and sixth principles, requires regard to be had to a two (or more) day consecutive pattern: i.e., to determine that a B shift will not be preceded by an A or C on what (logically) is the day preceding the day of the B shift.
97I agree with Basten JA that his Honour did not err in having regard to the Scheduling Principles. The application of the Scheduling Principles (assuming they are followed correctly) must logically produce a pattern as to how each particular day's shifts are configured. Where I differ from Basten JA is that I consider that the pattern produced by the Scheduling Principles is one that involves a temporal configuration. The pattern commences with the "B" shift and generally follows the order B, A, C (with some variation if there is an E or D shift). That configuration takes as the first shift of the day the "B" shift (as per the diagrammatic representation referred to earlier). This pattern is consistent with Mr Thorsby's evidence in the Industrial Court proceedings as to the current and long standing practice when scheduling work rosters over a 28 day period.
98That has two consequences. It means, first, that the requirement for 28 day rostering purposes, that a B shift not be preceded by an A or C shift (i.e., the fifth principle) is not relevantly part of the "daily" roster pattern since the B shift is the first of the day and logically cannot be preceded by an A or C shift that day; and, second, that a C shift one day might be followed by an A shift the next calendar day without triggering an entitlement to overtime.
99No daily roster complying with the B, A, C shift general configuration could, logically, breach the fifth, sixth or seventh principles (since those principles require attention to be had to the preceding day's roster).
