Consideration
30 In Telstra the Court explained the reach of the concept of prejudicial alteration at [17] - [18] as follows:
17 The question is whether, by sending the e-mail to its recipients, Telstra had altered the position of any of its employees to the employee's prejudice within the meaning of s 298K(1)(c). In Patrick Stevedores at 18 the majority of the High Court held that the subsection covers "not only legal injury but any adverse affection of, or deterioration in, the advantages enjoyed by the employee before the conduct in question". The majority also observed (at 20) that the reorganisation of companies within the Patrick Group resulted in the security of the employer companies' businesses being "extremely tenuous" with the "security of the employees' employment [being] consequentially altered to their prejudice". The reorganisation did not directly affect or alter any legal rights or obligations of the employees but it left their future employment less secure. Although this issue was not in dispute, the majority appears to have had no difficulty in accepting reduced security of future employment as falling within s 298K(1)(c) because it brought about an adverse affection of, or a deterioration in, the advantages enjoyed by the employees before the reorganisation.
18 Where the alteration of position is alleged to be indirect or consequential, as in Patrick Stevedores and in the present case, a difficult question may arise as to whether a prejudicial alteration of position has in fact occurred. Answering that question may involve questions of degree. It is sufficient for present purposes to say that if the prejudicial alteration is real and substantial, rather than merely possible or hypothetical, it will answer the description in s 298K(1)(c).
[emphasis added]
31 Australasian Meat Industry Employees Union v Belandra Pty Ltd 126 IR 165; [2003] FCA 910 is an example of a prejudicial alteration which occurred even though the employees in question suffered no loss or infringement of a legal right. The employees were meat workers whose employment was terminated when their employer's premises were destroyed by fire. The employer told them they would be re-employed when the operation resumed. However, the employer subsequently decided not to resume that operation and not to re-employ those employees. The employees had no legal right to re-employment. The statutory provision prohibiting prejudicial alteration applied to them and it was held that the disappointment of their expectation was an alteration of their position to their prejudice.
32 The authorities thus establish that a prejudicial alteration to the position of an employee may occur even though the employee suffers no loss or infringement of a legal right. It will occur if the alteration in the employee's position is real and substantial rather than merely possible or hypothetical.
33 By way of addition to or refinement of these principles, the first appellant argued that an employer's decision will only prejudicially alter the position of an employee if the employee falls within the cadre of people targeted by the decision. The addition or refinement is consistent with the purpose of the section, namely, to protect employees from disadvantageous actions of their employers.
34 The key question is whether the addition or refinement assists the first appellant in this case. In the end the answer depends on the time at which the facts are examined. The first appellant does not contest the finding of the federal magistrate that there was no temporal limit on the suspension when it was first put in place. It accepted that, at that time, the suspension was to operate without any end point. It is also common ground that Mr Murray expected an overseas posting towards the end of 2010 or early 2011. At the time the suspension was initiated this expectation could not be met because the suspension was not limited to a time before Mr Murray's next overseas posting was anticipated. Thus, if the facts are assessed at the time when the suspension was imposed and if, at that time, there was no temporal limit on the suspension, then Mr Murray fell within the cadre of persons affected by the suspension, and, even by applying the addition or refinement contended for by the first appellant, Mr Murray's position was prejudicially affected by the suspension of overseas postings.
35 The first appellant then argued that the finding that there was no temporal limit on the suspension must be read in the context of the finding that Mr Thompson believed the problem could be resolved quickly, and that he had no intention of permanently suspending postings from Brisbane. So understood, the evidence was that the suspension would be of short duration. It would not last until the end of 2010 or early 2011 and would not therefore impact on Mr Murray.
36 There are two difficulties with this approach. First, the duration of the suspension envisaged by Mr Thompson was not specific. Even if it is accepted that the suspension was not to be permanent and that it would be over quickly there is no clarity whether the suspension would still be in place when Mr Murray expected his next posting. There is insufficient precision in this description to support a finding that Mr Murray would not be impacted by the suspension. Second, the evidence only concerns Mr Thompson's belief as to the likely duration of the suspension and not the terms of the suspension conveyed to the employees.
37 Then it was said that the subject of the declaration was the suspension of overseas postings and that suspension actually occurred from 26 March 2010 to 27 April 2010. Mr Murray did not expect an overseas posting within the period of the actual suspension and was therefore not impacted by the decision. It follows that his position was not altered to his prejudice.
38 Again, this analysis takes the end of the period of the suspension as its vantage point. It assumes that the impugned action is that of imposing a suspension for a defined period ending before there was any impact on Mr Murray. But this was not the action about which a complaint was made, nor the action on which the declaration was based. The complaint was made over the imposition of a suspension for an unlimited period. The first appellant cannot recast the allegation into a form which, by its formulation, removes the prejudicial effect of the action.
39 Whilst the period of the suspension remained unlimited Mr Murray was prevented from obtaining overseas postings at the end of 2010 or early 2011 as he had previously expected to be able to do. The effect of this suspension in this period was therefore real and substantial and was not hypothetical or insubstantial. There was an adverse affection of and deterioration in the advantage enjoyed by Mr Murray before the suspension was imposed. Mr Murray was one of the employees to whom the suspension was directed.
40 It follows that the federal magistrate did not err in finding that the suspension of unlimited duration of overseas postings altered the position of Mr Murray to his prejudice. A declaration to reflect this finding was justified.
