Article 25
1. A member of temporary staff who receives orders which he considers to be irregular or likely to give rise to serious difficulties shall inform his immediate superior, who shall, if the information is given in writing, reply in writing. Subject to paragraph 2, if the immediate superior confirms the orders and the member of temporary staff believes that such confirmation does not constitute a reasonable response to the grounds of his concern, the member of temporary staff shall refer the question in writing to the hierarchical authority immediately above. If the latter confirms the orders in writing, the member of temporary staff shall carry them out unless they are manifestly illegal or constitute a breach of the relevant safety standards. 2. If the immediate superior considers that the orders must be executed promptly, the member of temporary staff shall carry them out unless they are manifestly illegal or constitute a breach of the relevant safety standards. At the request of the member of temporary staff, the immediate superior shall be obliged to give such orders in writing. 3. A member of temporary staff who informs his superiors of orders which he considered to be irregular or likely to give rise to serious difficulties shall not suffer any prejudice on account of this.
