"STAFF NOTICE WORKED REST DAYS AND OVERTIME Further to our earlier notice, please note that with effect from SATURDAY 15th AUGUST no worked rest days or pieces of overtime will be allocated unless the driver concerned has signed an Opting Out Agreement form (copy attached). This follows adverse comments made by our Internal Audit team after their June visit. In order to clarify any potential misunderstandings, please note that there is no compulsion to sign this form and signatories may, at any time, give six weeks notice to terminate the opt out. A majority of staff have already done so but if you have not already expressed a preference please let a Garage Supervisor know as soon as possible. If you have any other questions or concerns please speak to either a Garage Supervisor or Manager...."
"[…] As I have no intention of breaching the op[sic.] out agreement, you therefore cannot penalise me in the shape of refusing or not permitting me to work one rest day a week. Again you are attempting to break the Employment Laws, contracts between the employer and employee and you threaten blackmail if the employee does not sign it. I have consulted my daughter who is University graduate in law, Union solicitors in employment laws and also Roger Dillon, who I do believe you know. I am backed 100% by these people in what I am saying to you in the respect that you cannot blackmail or force someone into signing something they do not have to sign. I hereby put you on notice on the above and that I will take legal action against Arriva if I am penalised in any way, shape or form."
"21. The Tribunal found that it was agreed by all the witnesses that the Claimant did not sign an opt out agreement and as a direct consequence he lost out on the opportunity to work working rest days. The Tribunal therefore found that the Claimant did suffer a detriment."
"22. The Tribunal then considered whether the Claimant had been subjected to this detriment on the prohibited ground. The Tribunal was invited to consider this question in one of two ways. The Claimant's case was that the Claimant had refused to sign the opt out and this was the reason for the detriment. The Respondent's case was that the reason for the detriment was the employer's duties under Regulation 4 of the Working Time Regulations. The Tribunal noted that although both parties' Counsel had made reference to reasonableness, the only reference to reasonableness in the statutes was under Regulation 4 of the Working Time Regulations and this referred to the Respondent's duties in respect of controlling working hours and not to any question of detriment. 23. The Tribunal therefore concluded, as a straightforward matter of causation, that the detriment was caused by the Claimant's failure to sign the opt out. It was clear from the evidence of Mr Robinson that the sole reason for the withdrawal of working worked rest days was the Claimant's refusal to opt out. The Tribunal therefore concluded that the detriment had been applied on the ground of the Claimant's refusal to forego his rights contrary to section 45A."
