"The majority say [the failure to accept the terms] was because [the appellants] had failed to offer him the revised Contract of Employment, but in view of his status as a permanent employee they should have done so. Their failure to do so was in breach of their implied duty of trust and confidence and in particular their duty to treat employees in a fair and even handed manner. The majority say that [the appellants] should not be permitted to rely upon their own breach of contract."
"The question the Employment Tribunal had to answer was whether it was a breach of contract to deny Mr O'Brien the opportunity of entering a revised contract of employment with enhanced redundancy terms. There was no reason for excluding him, other than the fact that it was not realised that he was a permanent employee. The simple approach in fact is to note that if it had been appreciated that he was a permanent employee, he would have been offered the enhanced terms. If it was a breach not so to regard him, he must be placed in the position he would have been had the contract been fulfilled. He would have had the offer."
"... to offer a particular benefit to the entirety of a class of employees bar one is capable of being an act calculated seriously to damage or destroy the trust and confidence between the employer and that one employee."
