45 In relation to urgent work, the respondent contended all of its work was urgent and, therefore, apparently, the use of casuals had no limitation except that provided by s 7(3). I accept that the work of correctional officers is very important, but one would not, in ordinary parlance, describe it as 'urgent'. If I were to accept that all of the work of correctional officers was urgent then s 38(3)(a) to (c) would be otiose. I do not accept that the respondent, in the normal course, is able to rely on s 38(3)(d) to justify using casuals to fill long-term vacant officer positions. That is not urgent work.
46 On the question of 'work', the applicant submitted a casual may not be employed, even on an irregular or intermittent basis, to perform work that is not itself of an irregular or intermittent in nature (unless the work otherwise falls within paragraphs (b) to (d) of s 38(3)). Thus, it was submitted, whether s 38(3)(a) is applicable in any given situation requires an analysis of the nature of the work undertaken or to be undertaken by the casual. The same was said to apply to s 38(3)(d): the work itself to be performed by the casual must be of an urgent or emergency nature.
47 I do not accept the proposition that the work itself must be of an irregular or intermittent nature in order for it to be work a casual employee may do. There is no basis upon which to take such a restricted view of s 38. If one were to do so it would mean that a casual employee could not perform the work of an officer in a Department on those occasions the officer was unexpectedly absent on a day or shift because the normal 'work' of that officer would be regular or continuous and not irregular or intermittent. In such circumstances reliance could not be placed on s 38(3)(b) or (c), nor in most cases in the public sector on s 38(3)(d). In my opinion, 'work' as it is used in s 38(3) does not refer to the nature of the work, but rather the availability of the work to be carried out. If the work is only available on an irregular or intermittent basis, as opposed to regular or continuous work, for example, it will be work a casual employee may perform; it will be work available to be carried out on a casual basis.
48 The Guidelines provide: 'A person may be engaged as a casual employee on a genuinely irregular and [sic -or] intermittent basis over a long period of time to meet "needs, relief or demands requirements".' This suggests that it is the availability of the work that is irregular or intermittent, not the tasks or duties performed by the casual employee.
49 As I earlier noted, the Guidelines further state: 'Where a person works irregular and [sic - or] intermittent hours each week or roster period, irrespective of the time period the employment is over (may be years), employment would in most instances be as a casual employee under s 38.' This also suggests that a casual employee may be engaged pursuant to subsection 38(3)(a) of the PSEM Act to carry out work that is irregular or intermittent and, in doing so, perform work each week or roster period for a period that may extend over years.
50 It is apparent from what the Minister said in his second reading speech introducing the Public Sector Employment and Management Bill in 2002 that the Government was seeking to modernise the public sector's employment practices to provide for greater flexibility without compromising the usual method for employment in the public service, that being appointment as an officer. On casual employment, the Minister stated:
Casual work is justified in certain circumstances - for instance, when there are unplanned absences in critical front-line positions. It is defined as employment for work that is irregular or intermittent. Casual employment is to be used only when a department's workload needs to be addressed in the short term or in an urgent or emergency situation.
51 In my opinion, work will be irregular or intermittent in circumstances where planned or unplanned absences create occasional gaps in the regular or continuous work performed by permanent officers (or temporary employees) that need to be filled. The requirement to utilise casual labour to perform irregular or intermittent work may include the need to cover short-term unplanned absences caused, for example, by illness, filling the demand for additional labour caused by spikes in the normal workload, filling planned absences for short periods, and other work exigencies that may arise from time to time - irregularly or intermittently - that cannot be met by the permanent workforce.
52 What casuals may not be used for is a long-term substitute for employing officers either on a full-time or part-time basis or to avoid or deliberately and unjustifiably delay filling long-term vacant officer positions, other than in the circumstances allowed by s 38(3)(c). To do so would be inconsistent with s 7(3) of the PSEM Act. I agree with the applicant's submission that s 7(3) is to be interpreted as constituting a positive obligation upon public service departments to ensure that in all circumstances, the employment of officers is to be the usual mode of employment.
53 In summary, therefore, in answer to the construction issues contested in these proceedings:
(a) A person may be employed as a casual employee under s 38(3)(a) to carry out work that is irregular or intermittent. It is the requirement to perform work on an irregular or intermittent basis, not the nature of the work to be performed by the casual employee, which is determinative. There is no prohibition in the PSEM Act or the Guidelines against the engagement of casual employees to undertake the work of an officer, even if the position is vacant, except that casuals may not be used as a long-term substitute for employing officers or to avoid or deliberately and unjustifiably delay filling long-term vacant officer positions, other than in the circumstances allowed by s 38(3)(c).
(b) Where a person works irregular or intermittent hours each week or roster period, irrespective of the time period the employment is over (may be years), employment would in most instances be as a casual employee under s 38. A person may be engaged over a long period of time as a casual employee on an irregular or intermittent basis to meet needs, relief or demands requirements. The employment will usually be by the day or shift, but not necessarily so. An essential feature of this type of employment is that there will be no firm advance commitment as to the shifts the employee will work during the period of engagement. This will be evident from the terms of engagement, either expressed or implied, or by the employee not being obliged to accept an offer to work on a particular day or shift, or both.
(c) It was stated in Hamzy that the essence of casualness is the absence of a firm advance commitment as to the duration of the employee's employment or the days (or hours) the employee will work, but that is not inconsistent with the possibility of the employee's work pattern turning out to be regular and systematic. However, the Guidelines provide that: 'Casual employment should only be used in limited circumstances', the PSEM Act provides for temporary employees and the PSEM Act provides the usual basis of employment is that of officer. It would be inconsistent with s 7(3) of the PSEM Act and the Guidelines to allow a situation to develop whereby employees engaged as casuals on the basis of a contract of employment the duration of which was a shift, continued working over the long-term such that the work became regular or systematic or continuous (notwithstanding that the terms of the engagement provided the employee was not obliged to accept an offer to work on a particular shift) and this had the effect of being a substitute for appointing an officer. It would be a sham to regard this as casual employment under s 38(3)(a) of the PSEM Act because it would not be characterised by irregularity or intermittency. Simply because the contract of employment was on a daily or shift basis, does not give it the character of intermittency contemplated by s 38(3)(a) if what has evolved is a regular or systematic pattern of work whereby there is a tacit expectation of ongoing work being offered and accepted. Moreover, because a casual employee might fill a different post each shift worked or work at a different correctional centre in the same district, does not give the employment the character of irregularity or intermittency. The employee would still be a correctional officer working a regular or systematic pattern of shifts.
(d) The Guidelines provide that '[n]o single period of employment for a casual employee under s 38 shall exceed 3 months.' This necessarily implies, in the context of the Guidelines, that a short period or 'short-term' is three months or less. A long period of time for the purpose of (b) above may be, as the Guidelines indicate, years.
(e) If a person is employed for a single period not exceeding three months under s 38(3)(a), the work to be carried out in that period must be irregular or intermittent: see, for example, the respondent's pattern of employment in Ryde-Eastwood .
(f) A person may be employed under s 38(3)(b) as a casual employee to carry out work, on a short-term basis, in an area of CSNSW with a flexible workload. In view of the limit in the Guidelines of three months in respect of a single period of employment, 'short-term' may be regarded as a period of three months or less. A flexible workload would not extend to fluctuations in attendance at work by officers but relates only to fluctuations in workload that cannot be met be permanent staff.
(g) A person may be employed under s 38(3)(c) as a casual employee to carry out the work of a position for a short period pending the completion of the selection process for the position. The reference to 'selection process' is to the selection process prescribed by the PSEM Act in Pt 2.3. Section 38(3)(c) refers to 'the' selection process. The only selection process provided by the Act is a merit selection process. In view of the limit in the Guidelines of three months in respect of a single period of employment, 'short period' may be regarded as a period of less than three months.
(h) A person may be employed under s 38(3)(d) as a casual employee to carry out urgent work or to deal with an emergency. The normal work of a Corrections Officer cannot be regarded as 'urgent work' such that s 38(3)(d) may be used to justify the engagement of a casual employee under any or all circumstances.
(i) Section 7(3) of the PSEM Act is to be interpreted as constituting a positive obligation upon public service departments to ensure that in all circumstances, the employment of officers is to be the usual mode of employment. That is to say, before making any decision to engage a casual employee the department must give active consideration to whether an officer should be employed. In the alternative, the Guidelines provide for a single period in excess of four weeks involving fixed or regular hours, employment would, in most instances, be as a Departmental temporary employee.
