“33. It has been held by the EAT in Jones v Sirl and Son (Furnishers) Ltd[1997] IRLR 493 that in constructive dismissal cases the repudiatory breach by the employer need not be the sole cause of the employee’s resignation. The EAT there pointed out that there may well be concurrent causes operating on the mind of an employee whose employer has committed fundamental breaches of contract and that the employee may leave because of both those breaches and another factor, such as the availability of another job. It [is] suggested that the test to be applied was whether the breach or breaches were the ‘effective cause’ of the resignation. I see the attractions of that approach, but there are dangers in getting drawn too far into questions about the employee’s motives. It must be remembered that we are dealing here with a contractual relationship, and constructive dismissal is a form of termination of contract by repudiation by one party which is accepted by the other: see the Western Excavating case. The proper approach, therefore, once a repudiation of the contract by the employer has been established, is to ask whether the employee has accepting that repudiation by treating the contract of employment as at an end. It must be in response to the repudiation, but the fact that the employee also objected to the other actions or inactions of the employer, not amounting to a breach of contract, would not vitiate the acceptance of the repudiation. It follows that, in the present case, it was enough that the employee resigned in response, at least in part, to fundamental breaches of contract by [the employer].”
“34. … On that analysis it appears that the crucial question is whether the repudiatory breach played a part in the dismissal. There must be a causal connection between the repudiation and the resignation; if they are unconnected acts then the employee is not accepting the repudiatory breach. 35. It follows that once a repudiatory breach is established, if the employee leaves then even if he may have done so for a whole host of reasons, he can claim that he has been constructively dismissed if the repudiatory breach is one of the factors relied upon. We respectfully agree with this reasoning. We think it would be invidious for tribunals to have to speculate what would have occurred had the employee been faced with the more limited grounds of legitimate complaint than he had perceived to be the case. 36. Moreover, if there is a repudiatory breach which entitles the employee to leave and claim constructive dismissal, we see no justification for allowing the employer to avoid that consequence merely because the employee also relies on other, perhaps unjustified or unsubstantiated, reasons. The employee ought not to be in a worse position as a result of relying on additional, albeit misconceived, grounds. 37. Accordingly, although it is true that the Tribunal did not in this case specifically engage with the question of whether there was a causal link between the repudiatory breach and the dismissal, that was no doubt because in the circumstances of this case this appeared not to be in dispute. It was never suggested that the employee did not resign because of the list of grievances that he set out in his letter. It follows from the reasoning in the Meikle case that if any of those matters constituted a repudiatory breach, the resignation would be enough to establish the constructive dismissal.”
“11. Jones … itself is a case which unhappily lends itself to an interpretation of the words ‘the effective cause’ as if the search was for the principal or main cause rather than simply a breach which a response to which in part led to the resignation. In the judgment of the Appeal Tribunal delivered by Judge Colin Smith QC it is said at paragraph 10 that the industrial tribunal must look to see whether: ‘… the employer’s repudiatory breach was the effective cause of the resignation. It is important, in our judgment, to appreciate that in such a situation of potentially constructive dismissal, particularly in today’s labour market, there may well be concurrent causes operating on the mind of an employee whose employer has committed fundamental breaches of his contract of employment entitling him to put an end to it. Thus an employee may leave both because of the fundamental and repudiatory breaches, and also because of the fact that he has found another job. In such a situation, which will not be uncommon, the industrial tribunal must [find] out what the effective cause of the resignation was, depending on the individual circumstances of any given case.’ 12. Insofar as that passage suggests that the tribunal must choose between causes, both of which operate, in order to see which was the predominant one, it is in error. If it is saying that the evidence may leave the tribunal in a circumstance in which it is plain that the behaviour was not in response to a breach, even though that occurred and even though it was serious, but for some other unconnected reason to the exclusion of a response to the breach, then it would be correct. It is a pity that ambivalence has obscured the principle underlying the decision, which was clearly identified in Meikle and is therefore and in any event binding upon this tribunal.”
“81. Once repudiation of the contract by the employer has been established, the proper approach is then to ask whether the employee has accepted that repudiation by treating the contract of employment as at an end. It is enough that the employee resigned in response, at least in part, to a fundamental breach by the employer. …”
“88 … In our judgment, the unexplained decision of the respondent to put the claimant back on duty 305 with effect from6 January 2014 was a continuing and fundamental breach of the implied term until the date of the claimant’s resignation. The respondent knew full well that the claimant was unfit for those duties. …”
“97. The key issue therefore is whether or not the claimant resigned by reason of the fundamental breaches that he has established or for some other reason. The respondent says that he resigned in order to avoid facing disciplinary action about the incident of1 March 2014 . We find that he did so and that the real reason for the resignation was not in response to the fundamental breach that he has established. Save for the issue of pressure to consider part time working or ill health retirement and the rostering on unsuitable routes prior to14 October 2013 the fundamental breaches that he has established were continuing from6 January 2014 (when he was rostered back to route 305). In these circumstances, the claimant would have us believe that it was simply a coincidence that he resigned in response upon the very day that he was due to view CCTV footage of the incident of1 March 2014 . That contention stretches the Tribunal’s credulity to the limits. Therefore, although the claimant has established a fundamental breach of the implied term the operative cause of the resignation was not that breach but rather a desire to avoid the disciplinary issue that arose. It follows therefore that the constructive unfair dismissal complaint fails and stands dismissed.”
“6. In my judgment, the reconsideration application has no reasonable prospects of success. There is simply no prospect of the claimant establishing that the reason for his resignation was the fundamental breaches of contract on the part of the respondent which he established as opposed to his resigning in an effort to avoid the disciplinary action that was inevitably going to follow following the incident of1 March 2014 . 7. As we have said in our reasons, it is simply too much of a coincidence that the claimant decided to resign on the very same day upon which he was invited to review the CCTV footage and not before in circumstances where the fundamental breach had continued from the date of the Occupational Health physician’s report of17 September 2013 .”
