"4. The Applicant has been employed by the Respondent since 1984. He is currently a train guard conductor. The Applicant and his former partner have a two year old son who lives with the Applicant's ex-partner. In or about the middle of June 2003 the Applicant's ex-partner informed him that she needed to visit her disabled sister on Saturday 26 July and it would therefore be necessary for the Applicant to look after his son on that day. The Applicant applied for annual leave on 26 July. He was told that it might be possible to grant him leave but it could not be guaranteed. Because of that uncertainty on 5 July he made a written application for parental leave on 26 July for the purpose of caring for his son. He received no written response from the Respondent to that request. 5. On Thursday 24 July the Applicant was told that he could not take 26 July as parental leave because his job could not be covered. He enquired about the position again on 25 July and was told that a manager would speak to him, but he received no response. On 24 and 25 July the Applicant made clear to his managers that he would not attend work on 26 July because he had to look after his son. 6. The Applicant did not come to work on 26 July and spent the day caring for his son. On 8 August he received a document called Form 1 charging him with the disciplinary offence of being absent without permission. The sanctions available to the Respondent pursuant to the Form 1 disciplinary procedure range from a reprimand to dismissal. The Applicant attended a disciplinary hearing on 24 September accompanied by his trade union representative. The hearing lasted approximately 5 hours. In the course of the hearing the Respondent's managers made a number of allegations that are longer relied upon by the Respondent. For example it was suggested that the Applicant had never submitted an application for parental leave. It was also contended that the Respondent had entered into a collective agreement about parental leave with the Applicant's trade union the RMT. That contention is no longer relied upon by the Respondent. 7. The manager conducting the disciplinary hearing decided to withdraw the Form 1 charge but to give the Applicant a warning about his non-attendance for duty on 26 July. On 29 September the manager sent the Applicant a letter confirming that decision. The letter included the following sentence:- "
"26. The Tribunal agreed with the Applicant that charging him with a disciplinary offence, requiring him to attend a disciplinary hearing, and giving him a warning all constituted a detriment. In particular, the giving of a warning confirmed in writing constituted a detriment. 27. We next considered whether the Applicant was subjected to that detriment for a prescribed reason. The reason that the Applicant was subjected to the detriment was because of a disagreement about his entitlement to parental leave. That reason related to parental leave. We therefore concluded that the detriment was done for a prescribed reason. We concluded that the Applicant's complaint was well-founded. 28. In arriving at that conclusion it is apparent that we did not accept Mr Todd's submission that because as he submitted, the Applicant was not entitled to parental leave on 26 July, the detriment could not have been for a reason which related to parental leave. In case we are mistaken in our view, we went on to consider whether the Applicant had in fact been entitled to parental leave on 26 July. 29. In our view we must adopt a purposive approach to the Regulations. The purpose of the Council Directive is to allow for "better organisation of working hours and greater flexibility, and to allow for the "reconciliation of work and family life"
"7. An employee may not take parental leave in a period other than a period which constitutes a week's leave for him under Regulation 14 or a multiple of that period, except in a case where the child in respect of whom leave is taken is entitled to a Disability Living Allowance"
