"... the air quality in her new work place was much worse than in her former place and it was source of nuisance and discomfort her."
"The result was that, for a non-smoker, the air was not of a reasonably tolerable quality. Some days were worse than others and, when Mrs Dorrington was particularly affected by the smoky atmosphere, she was allowed, by Mr Langley [ her immediate superior ], to leave the building for 'fresh air'. She did not regard it as acceptable and she made her views known."
"Mrs Dorrington was entitled to be, and she was, upset by this apparent reversal of a decision and she took matters up with Mr Geaney. Among the options she wished to consider was to work for someone else in another part of the building. Mr Langley was, throughout, supportive of Mrs Dorrington and he had made it clear that he could see no objection to a move along the corridor and where he could retain her services. The arguments against that were related to administrative convenience and efficiency and, if the freedom of those who chose to smoke in the shipping area were not to be further curbed, the balance lay firmly in favour of the proposed move. The little inconvenience which would have resulted was heavily outweighed by the legitimate concerns of those non-smokers who sought a tolerable working environment; no reasonable employer, on the facts of the case, could have concluded otherwise."
"... there was no more to be done, and in effect, that she would have to put up with the situation or 'do the other thing'."
"We propose to hold that it is an implied term of every contract of employment that the employer will provide and maintain, a working environment which is reasonably tolerable to all employees. It is such an obvious requirement that a party to an employment contract, were they to address their minds to the point, would assume that such must have been intended to be the case. Such a term must apply to such matters as noise levels, smells and the quality of the air which the employees breathe; not to the same standard as may be expected of a Cotswold meadow in summer but to a standard which is reasonable bearing in mind the nature of the employers' business and its location. In this case, it is the standard reasonably to be expected of offices premises in central London."
"The E.A.T., in W A Goold (Pearmak) Ltd v. McConnell[1995] IRLR 516 held that it is an implied term in a contract of employment that the employers will reasonably and promptly afford a reasonable opportunity to their employees to obtain redress of any grievance they may have. That was a fundamental right and a failure, promptly or properly, to address such a grievance might constitute 'constructive' dismissal."
"(2) ... the inadequacies of the ventilation created a situation in which the air quality, to the reasonable standard of a non-smoker, was intolerable. The risks of 'passive smoking', as such a situation is commonly known, are so well known as to require no further proof. It is not sufficient, as the respondents sought to do, to balance the interests of smokers with non-smokers so that each was to be accorded equal weight. The choice of an individual not to smoke has not detrimental impact upon those in close proximity, whereas the reverse is not also true. It is, therefore, neither fair nor accurate to describe the curbing of the freedom to smoke as treating the non-smoker 'more favourably', as the respondents suggest."
"(4) The respondents throughout, have proceeded upon the assumption that the concerns which Mrs Dorrington had raised did not fall within their grievance procedure."
"She had raised a matter about which she was reasonably entitled to feel concerned and the implied term, as identified above, required that the respondents timeously and properly dealt with it. They did not do so."
"... herself a self confessed 'heavy smoker', has observed that she could recall no instance, from a wide industrial experience, in which an employer had so leant in favour of accommodating a smoking lobby."
"(5) The air quality in the area in which Mrs Dorrington was required to work was not of a standard which was reasonably tolerable to a non-smoker."
"They were reasonably entitled to decide the deployment of their staff and to have regard to the requirements of efficiency and administrative convenience."
"... was to place those considerations above the fundamental requirement that they provide a working environment which was reasonably tolerable ..."
"If there really was no practicable solution, about which we were not persuaded, then it was the activities of the smokers which had to be curbed. To say to Mrs Dorrington, as the respondents did, - 'There is no more to be done, accept it or leave' - was, we consider, a breach of both the term as to the provision of a reasonably tolerable working environment and as to the proper addressing of the concerns which she had raised. That was a serious breach of a fundamental obligation of an employer and Mrs Dorrington reasonably concluded that she was being forced to resign; it was a repudiatory breach of such seriousness as to justify her in leaving at once."
"Although we were not referred to the cases outside the field of employment law, our own researches have led us to the view that the general principles applicable to a repudiation of contract are as follows. If one party ("the guilty party") commits a repudiatory breach of the contract, the other party ("the innocent party") can choose one of two courses: he can affirm the contract and insist on its further performance or he can accept the repudiation, in which case the contract is at an end. The innocent party must at some stage elect between these two possible courses: if he once affirms the contract, his right to accept the repudiation is at an end. But he is not bound to elect within a reasonable or any other time. Mere delay by itself ( unaccompanied by an express or applied affirmation of the contract) does not constitute affirmation of the contract; but if it is prolonged it may be evidence of an implied affirmation. ... Affirmation of the contract can be implied. Thus, if the innocent party calls on the guilty party for further performance of the contract, he will normally be taken to have affirmed the contract since his conduct is only consistent with the continued existence of the contractual obligation. Moreover, if the innocent party himself does acts which are only consistent with the continued existence of the contract, such acts will normally show affirmation of the contract. However, if the innocent party further performs the contract to a limited extent but at the same time makes it clear that he is reserving his right to accept the repudiation or in only continuing so as to allow the guilty party to remedy the breach, such further performance does not prejudice his right subsequently to accept the repudiation."
"There is no fixed time limit within which the employer must make up his mind. It depends upon all the circumstances including the employee's length of service, the nature of the breach and whether the employee has protested at the change. Mere protest will not however prevent an inference that the employee has waived the breach, although exceptionally a clear reservation of a right might do so. Where the employee is faced with giving up his job and being unemployed or waiving the breach, it is not surprising that the Courts are sometimes reluctant to conclude that he has lost his right to treat himself as discharged by the employer merely by working at the job for a few months."
"(7) We were concerned at Mrs Dorrington's delay in acting upon the breach. On balance, we have decided that it was not such as to amount to an affirmation of the contract. She informed her immediate boss that she was looking for another job and she had made clear that the working environment and the failure properly to address her concerns were the reasons for doing so. Her need to maintain her income was a factor which she was reasonably entitled to place in the balance. When she did leave she made crystal clear the reasons for doing so and she not, in the interval, given the respondents any reasonable grounds for concluding that she had decided to accept the situation."
