73 In the evidence there was continual reference to the terms of the Enterprise Agreement which dealt with the concept of a "stock out". This matter had formed part of Clause 9 of the Agreement dealing with regulations of disturbances to production and supply. The immediately relevant parts of Clause 9 are:
9 . REGULATION OF DISTURBANCE TO PRODUCTION AND SUPPLY
9.1 Objects of this Clause
9.1.1. One of the key pillars that supports the ability of the Companies to have an effective and efficient business is the ongoing compliance by the parties and all employees with the obligations in this clause in respect of hot metal arrangements and meeting urgent customer needs.
9.1.2 The commitment and compliance with the obligations prescribed in this clause are significant in that they recognise the paramount importance of satisfying the Companies' customers each and every day and the close linkage between customer satisfaction, business performance and employment security. In addition they recognise the importance of protecting the security and integrity of the Companies' assets and not wastefully destroying product.
9.1.3 The parties recognise that to achieve these goals and maintain secure employment, they must manage their differences without allowing these differences to result in the destruction of product or major disruption to the Companies' customers.
9.1.4 The parties understand that only by satisfying customers and developing markets can the Companies deliver the desirable benefit of ongoing security of employment.
9.1.5 The obligations to comply with the arrangements contained in this clause in respect of hot metal and meeting urgent customer needs does not restrain, or seek to restrain, the taking of industrial action which does not result in non-compliance with those obligations. The parties are however committed to working together to provide a workplace where issues are resolved without recourse to industrial action.
9.1.6 The obligations imposed by this clause require that employees covered by this Agreement perform as directed the necessary work (for the purposes of this clause) which is part of their usual duties and are not to be taken as requiring 'staff' employees to undertake such work instead of employees covered by this Agreement.
…
9.1.9 Similarly, the proposal for the meeting of urgent customer needs does not require all product to be distributed but rather only that part of it requiring urgent despatch and subject to the provision of information and appropriate consultation as specified in this clause.
9.2 Compliance with this Clause and Linkage with Employment Security
9.2.1. There must be strict compliance by all parties with the terms of this Agreement concerning hot metal arrangements (sub-clause 9.3) and meeting urgent customer needs (sub-clause 9.4) during the course of any industrial action. There must be no breaches of these provisions.
9.2.2 The taking of steps during the course of any industrial action in breach of these requirements would be a serious matter and one requiring significant and urgent attention in any dispute resolution process. Any breach would be a paramount consideration for the Commission in the exercise of its powers under the Act as to industrial disputes.
9.2.3 A breach of the provisions concerning hot metal arrangements (sub-clause 9.3) and meeting urgent customer needs (sub-clause 9.4) may result in the removal (in part or whole) of the employment security provisions specified in clause 8 of this agreement. Any such removal shall not relieve the employees concerned of their obligations to comply with the requirements of this clause 9.
9.2.4 An application to remove the benefits of security of employment from any employees may be made by the relevant Company by notification under the Act of an industrial dispute. The Companies shall bear the onus of making out a case for such removal. The determination of such an application shall be governed by the considerations referred to by the Commission in the Recommendation of Walton J - Vice President, dated 13 May 2002, particularly at paragraph 95. The Commissioner's determination shall be binding on the parties.

9.4 Meeting Urgent Customers Needs
9.4.1 To satisfy the requirements of the customers of the Companies, the parties are committed to ensuring that the urgent needs of customers are met throughout the period of any industrial dispute.
9.4.2. In recognising that the Companies' customers are a key foundation of the Companies' business, the parties commit to the principle that all disputes and issues will be resolved in accordance with the applicable dispute resolution procedures and without recourse to industrial action that would adversely impact on those customers.
9.4.3 In the unlikely event of industrial action occurring, the parties will, before such action commences, and on an ongoing basis as necessary during such action, hold discussions in relation to production or maintenance work that is necessary to enable genuinely urgent customer requirements to be met. So far as practicable, prior to the taking of industrial action and (on all occasions) progressively, as necessary, during such action the relevant union delegate(s) and the relevant Company representatives will meet and confer immediately and on an ongoing basis to manage the supply of product to avoid stocking out of customers.
9.4.4. The Company's customer service or logistics representative will identify product that is required to maintain a customer's business and is packed and waiting despatch.
9.4.5. Where, in accordance with sub clause 9.4.6. and 9.4.7, product is identified as requiring despatch to avoid a stock out or potential stock out and that product or part of that product is packed and awaiting despatch, it will be despatched as required by the Company.
9.4.6. The company will become aware, either through its despatch management systems or by way of other direct communication with a customer that the customer is in need of urgent delivery of product to avoid a stock out. This will occur each and every day during a period of industrial action.
