“15. … Here, we think the claimant has established that a significant part of his role was removed. It was the exclusivity which he had in relation to the design of large infrastructure projects. It is not surprising that the respondent would wish to take stock of the proposed projects already in existence and want to implement different projects of their own. The project they pursued, in units 6-8 was a project in which the claimant did not have sole responsibility for design and development. His role continued insofar as it related to the project management of installations specifically in May and June 2015, in relation to unit 5. He had some input into the new project, but his involvement was not the same. In effect Mr Butler now had leadership of that project and there was a project team within the respondent responsible for the development of the project, whereas before the sale the claimant had sole responsibility for those matters. …”
“16. … This case is pleaded as a breach of the implied duty to maintain trust and confidence. In the light of that, the respondent is in our judgment entitled to say that the tribunal must consider whether or not they had reasonable and proper cause for the actions which they took in relation to the claimant’s work.”
“17. Our view in relation to this is that the conduct of the employer not only includes their decision as to how to conduct major projects for the future but also how, if at all, their decision is communicated to the workforce they inherited on the transfer. It is a defence available to the respondent if they can show that they had reasonable and proper cause for the actions they took, to which the claimant objected. It could be no part of their reasoning to exclude the claimant from sole responsibility for project development because he was incompetent to do it. All the respondent’s witnesses say that they had the utmost respect for his abilities. The only reason they could have for adopting the project team approach, led by Mr Butler, in relation to the new project was that that was how Johnson Service Group manage such projects. They are a plc, but any company is entitled to have its own methods for the management of projects. Adopting that methodology is not unreasonable. The communication of how this was to be undertaken was almost non-existent, although the claimant was able to deduce how the new owners were going to operate from their actions. The tribunal cannot identify any reasonable or proper cause for the respondent failing to inform the claimant at an early stage that was how they intended to conduct their project operations. To that extent, their conduct was without reasonable or proper cause. 18. We both agree that the absence of effective communication was bound to affect the claimant’s trust and confidence in his new employers. Whether that consequence was sufficient to destroy or seriously damage his trust and confidence is a question that we find difficult to answer. …”
“18. … However, we are of the view that the claimant did not resign his employment because of the way in which the respondent communicated its decision as to how projects would be managed in the future (and indeed this matter was not specifically pleaded). It was the decision itself, to remove from the claimant sole responsibility for new projects and to assign that responsibility to a project team, of which he was merely a member, which caused the claimant to resign. This removed responsibilities from him, although it did not affect his job title, because he would remain an industrial engineer. Although this new method of working significantly affected the claimant’s role and responsibilities, our view that the employer had reasonable and proper cause to adopt that methodology means that there was not a breach of contract which led to the claimant’s resignation. Although he resigned because of that, it was not a breach of contract. He did not resign because of the poor communication of the decision. For the sake of completeness, we do not think that the claimant resigned because he thought that the payment of£30,000 was inadequate. …”
“18. … Our view is that the claimant wanted to work, and to be fully engaged in work, until October 2017 and that the new method of working denied him the responsibilities and status which he had enjoyed until the sale. But that did not amount to a breach of contract as the case has been pleaded and the only potential breach is a matter which was not pleaded and which did not prompt the claimant to resign. For those reasons, he was not constructively dismissed.”
“17. In our view it is clearly established that there is implied in a contract of employment a term that the employers will not, without reasonable and proper cause, conduct themselves in a manner calculated or likely to destroy or seriously damage the relationship of confidence and trust between employer and employee: Courtaulds Northern Textiles Ltd v Andrew[1979] IRLR 84 . To constitute a breach of this implied term, it is not necessary to show that the employer intended any repudiation of the contract: the Tribunal’s function is to look at the employer’s conduct as a whole and determine whether it is such that its effect, judged reasonably and sensibly, is such that the employee cannot be expected to put up with it: see British Aircraft Corporation Ltd v Austin[1978] IRLR 332 and Post Office v Roberts[1980] IRLR 347 . The conduct of the parties has to be looked at as a whole and its cumulative impact assessed: Post Office v Roberts (supra) paragraph 50.”
“… the only potential breach is a matter which was not pleaded and which did not prompt the claimant to resign.”
