"4. Effect of relevant transfer on contracts of employment … (4) Subject to regulation 9, in respect of a contract of employment that is, or will be, transferred by paragraph (1), any purported variation of the contract shall be void if the sole or principal reason for the variation is - (a) the transfer itself; or (b) a reason connected with the transfer that is not an economic, technical or organisational reason entailing changes in the workforce."
"31. … if an electrician had to work from a depot other than his home depot this triggered the payment of ETTA subject to the submission of a form … and the authorisation of that form by a line manager."
"36. … by the time of the Mears Transfer each of the first second third and sixth claimants were contractually entitled to payment of ETTA at a daily rate of either one hour (the third claimant) or an hour and a half (the first second and sixth claimant[s]) subject to the submission of a form and the authorisation of that form by a line manager either because of acceptance inferred by conduct or custom and practice regularly applied over a number of years. …"
"38. … as a result of the then working practices of the electricians the respondent did not believe they were met [sic] what the respondent understood to be the eligibility criteria for entitlement to ETTA and decided no payments of ETTA would be made until the electricians could prove they were so entitled. …"
"With the clarity provided by the ET and EAT that the scheme is outdated and having fully reviewed the needs of the business, I can confirm that a decision has been taken that not only is the allowance … inappropriate, but also it fails to support our business needs going forward and it is wholly unfair on the remainder of the workforce who operate in exactly the same way as the [electricians] and who have not presented any claim to travel allowances. Regardless of whether or not you have or are currently attempting to exercise any right under this allowance, we can confirm that irrespective of whether the entitlement is an express or implied terms [sic] in your employment, this letter is notice that we no longer intend to be bound by it and we are therefore giving you a formal notice of the removal of this allowance from your Terms and Conditions of employment. Again, regardless as to whether or not the allowance is enforceable any entitlement to the allowance will cease on01 September 2012 and the allowance will no longer form part of anyone's Contract of Employment. If you have not been submitting monthly claims for travel allowances since the transfer to Mears in 2008, you will not notice any difference as a result of this decision and your terms and conditions remain largely unaffected."
"39. … I infer from its contents that once a tribunal and the EAT had found against it, the respondent decided to ensure that any such contractual entitlement was brought to an abrupt end because it believed that it was outdated in the light of the (by then very longstanding) working practices of the electricians. It would not countenance having to maintain a contractual entitlement to a fixed rate daily allowance to electricians the historic rationale for which had long since disappeared; the electricians did not lose productivity bonuses because of time spent travelling to a depot other than their home depot because there were no productivity bonuses and there was only one depot. This decision (to vary the contract by stopping the contractual entitlement) was not the same decision as the earlier decision to cease making ETTA payments some four years before nor was it taken for the same reasons, albeit the respondent's view that the ETTA payment was outdated is a common thread. I conclude the operative reasons for the variation (the adverse findings of the tribunal and EAT and the respondent's belief that the ETTA payments were outdated) were not the transfer itself or a reason connected with the transfer."
