"Circumstances in which an employee is dismissed (1) For the purposes of this Part an employee is dismissed by his employer if (and, subject to subsection (2) . .. , only if) – (a) …….. (b) …….. (c) the employee terminates the contract under which he is employed (with or without notice) in circumstances in which he is entitled to terminate it without notice by reason of the employer's conduct"
"If the employer is guilty of conduct which is a significant breach going to the root of the contract of employment; or which shows that the employer no longer intends to be bound by one or more of the essential terms of the contract; then the employee is entitled to treat himself as discharged from any further performance. If he does so, then he terminates the contract by reason of the employer's conduct. He is constructively dismissed."
“55. I am concerned that the foregoing paragraphs may make the law in this area seem complicated and full of traps for the unwary. I do not believe that that is so. In the normal case where an employee claims to have been constructively dismissed it is sufficient for a tribunal to ask itself the following questions: (1) What was the most recent act (or omission) on the part of the employer which the employee says caused, or triggered, his or her resignation? (2) Has he or she affirmed the contract since that act? (3) If not, was that act (or omission) by itself a repudiatory breach of contract? (4) If not, was it nevertheless a part (applying the approach explained in Omilaju[2005] ICR 481 ) of a course of conduct comprising several acts and omissions which, viewed cumulatively, amounted to a (repudiatory) 8 breach of the Malik term? (If it was, there is no need for any separate consideration of a possible previous affirmation, for the reason given at the end of para 45 above.) (5) Did the employee resign in response (or partly in response) to that breach? None of those questions is conceptually problematic, though of course answering them in the circumstances of a particular case may not be easy.”
“118. In considering the reasoning of the ET, I remind myself of the guidance provided by Popplewell LJ in DPP Law Ltd v Greenberg[2021] EWCA Civ 672 , [2021 IRLR 1016 at paragraphs 57-58, as follows (I summarise): (1) the decision is to be read fairly and as a whole, without focusing merely on individual phrases or passages in isolation, and without being hypercritical (an ET is not sitting an examination; see per Singh LJ paragraph 42 Sullivan v Bury Street Capital Ltd[2021] EWCA Civ 1694 ,[2021] IRLR 159 ); (2) the ET is not required to identify all the evidence relied on in reaching its conclusions of fact, nor express every step of its reasoning in any greater degree of detail than that necessary to be Meek-compliant (Meek v Birmingham City Council [1987] EWCA Civ 7,[1987] IRLR 250 ); (3) it should not be inferred that a failure to refer to evidence means that it did not exist, or was not taken into account: what is out of sight in the language of the decision is not to be presumed to be out of mind; (4) when an ET has correctly stated the legal principles, an appellate court should be slow to conclude that it has not applied those principles, and should generally only do so when it is clear from the language used that a different principle has been applied to the facts found – a presumption that ought to be all the stronger where the decision is that of an experienced, specialist tribunal, applying very familiar principles whose application forms a significant part of its day-to-day judicial workload”
‘(4) If not, was it nevertheless a part (applying the approach explained inOmilaju[2005] ICR 481 ) of a course of conduct comprising several acts and omissions which, viewed cumulatively, amounted to a (repudiatory) breach of the Malik term? (If it was, there is no need for any separate consideration of a possible previous affirmation, for the reason given at the end of para 45 above.) (5) Did the employee resign in response (or partly in response) to that breach?’
"The [EAT] can correct errors of law and substitute its own decision in so far as the [ET] must, but for the error of law, have reached such a decision. But if it is an open question how the [ET] would have decided the matter if it had directed itself correctly, the [EAT] can only remit the case for further consideration."
