"25. At the Hearing the Respondent put forward an alternative argument for withholding the Claimant's pay. This concerned paragraph 4.3 of the Claimant's Contract of Employment. This states:- 'It is a customer stipulation that we forward on to them the original daily worksheets duly authorised by their representative as proof of work done. Failure by the employee to submit the relevant signed daily worksheets will be construed as a job not being done. The company reserves the right to deduct the requisite hours from your wages accordingly.' 26. At the Hearing included in the Bundle of Documents were worksheets for each day of the week commencing4 February 2008 . These were the works carried out by the Claimant and his Labourer at the Humber Mental Health NHS Trust. The Respondent's argument is that since the Claimant failed to get these worksheets signed meant the Claimant was in breach of Paragraph 4.3 which entitled them to withhold his weeks' pay and his holiday pay. 27. The Claimant's argument was that he never previously had his worksheets signed. The Tribunal notes that the Respondent had not previously relied on this ground and there had been no reference to it in the correspondence or in the ET3. 28. The Claimant did submit these worksheets. The only shortcoming was they had not been signed by the client's representative. The Tribunal note that the Respondent never previously raised this as a ground for refusing the Claimant's payment. It was only at the Hearing in August 2008 that this provision was put forward as an alternative to justify the withholding of the last week's pay and the holiday pay. 29. The Contract of Employment was drafted by the Respondent's staff. Where there is ambiguity, the provision has to be construed against the Respondent. The provision only entitles the Respondent to deduct 'the requisite hours from your wages'. This would appear to be a provision intended to be applied immediately to a recalcitrant employee. It cannot be construed in such a way as to enable an employer some six months after the dismissal to use this clause to justify continuing refusal to pay the Claimant his pay for his final week of work or his 1.6 days holiday pay. 30. Accordingly the Tribunal is satisfied that the Respondent has not establish that they were entitled to deduct the entire amount of the Claimant's last weeks' wages or his holiday pay reliance on Clause 4.3 or 5.1 of his Contract of Employment."
