20 In other words, the test for manning disputes where there has been a change in the operations of BlueScope Steel is not strictly dependent on any general principles that have been developed in the Commission concerning manning but on the "safe, efficient, legal and fair test" set out in Clause 36 of the BlueScope Steel Award. But as I indicated in my unreported decision of Tuesday, 17 July, 2007 in the Tundish Repair Disputes Case [Matter No.IRC 3577 of 2007 at p.6]:
"...To my mind that does not mean that the AWU in this case must establish that a change that is being contemplated meets each and every one of the requirements of "safety", "efficiency", "legality" and "fairness". In my view, it would be absurd to suggest, for instance, that a change that is illegal but nevertheless efficient should still be permitted to occur: or permit a change that alone is unsafe to the employees. Each of the tests - safety, efficiency, legality and fairness - should be considered but any one of the tests may alone prove to be fatal to a proposed change. The Full Bench is not suggesting in Australian Workers Union v. BlueScope Steel (AIS) Pty Limited to read the 'safe, efficient, legal and fair test' as being cumulative: it is only emphasising the need to consider manning disputes in the context of Clause 36 rather than to otherwise rely on general principles relating to manning disputes..."
