"[480] Many of the constructive dismissal cases which arise from the undermining of trust and confidence will involve the employee leaving in response to a course of conduct carried on over a period of time. The particular incident which causes the employee to leave may in itself be insufficient to justify his taking that action, but when viewed against a background of such incidents it may be considered sufficient by the courts to warrant their treating the resignation as a constructive dismissal. It may be the 'last straw' which causes the employee to terminate a deteriorating relationship." 15. The last straw principle has been explained in a number of cases, perhaps most clearly in Lewis v Motorworld Garages Ltd[1986] ICR 157 . Neill LJ said (p 167C) that the repudiatory conduct may consist of a series of acts or incidents, some of them perhaps quite trivial, which cumulatively amount to a repudiatory breach of the implied term of trust and confidence. Glidewell LJ said at p 169F: "(3) The breach of this implied obligation of trust and confidence may consist of a series of actions on the part of the employer which cumulatively amount to a breach of the term, though each individual incident may not do so. In particular in such a case the last action of the employer which leads to the employee leaving need not itself be a breach of contract; the question is, does the cumulative series of acts taken together amount to a breach of the implied term? (See Woods v W. M. Car Services (Peterborough) Ltd .[1981] ICR 666 .) This is the "last straw" situation." 16. Although the final straw may be relatively insignificant, it must not be utterly trivial: the principle that the law is not concerned with very small things (more elegantly expressed in the maxim " de minimis non curat lex ") is of general application."
"The first issue remaining is whether the employer's whole course of conduct evinced persistent malicious allegations of harassment against the Applicant that in law constituted a breach of the duty of mutual trust and confidence."
"During the period of suspension you must not discuss the contents of this investigation or any information pertaining to the enquiries with any employees of the City Council, including the staff at Brandon Wood Farm. You must also not approach any Departmental Service Users to discuss the contents of this investigation or information pertaining to these enquiries."
"In our judgment, it is clear… that in order to decide whether an employee has left in consequence of fundamental breach, 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 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."
"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 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 a 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 accepted 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 NCC."
"…and on 18 September [2001] I felt I had no choice but to resign from the local authority's employment" and the fact that Mr O'Shea had made no mention of his seeking or having found another job before his resignation in either his IT1 or his original witness statement.. Those findings were at paragraph 16 of its original decision: "
"…did the Tribunal conclude, by reference to Jones v Sirl , that the alleged repudiation, if established, was not the effective cause of the termination of employment, and if so, why?"
