Breach of Contract in UK Law

The act does not have to be of the same character as the earlier acts. Its essential quality is that, when taken in conjunction with the earlier acts on which the employee relies, it amounts to a breach of the implied term of trust and confidence. It must contribute something to that breach, although what it adds may be relatively insignificant.

(c) 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?

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.

I accept Mr Lopian's submission that there can be cases of harmless collaterality. And that there can be cases where there is just an honest breach of contract such as Keppel. This is a case of a secret profit obtained because Mr Berry/Imageview was Mr Jack's agent. And there was a breach of a fiduciary duty because of a real conflict of interest.

One may safely say that the parties cannot, in a contract, have contemplated that the clause should have so wide an ambit as in effect to deprive one party's stipulations of all contractual force: to do so would be to reduce the contract to a mere declaration of intent. To this extent it may be correct to say that there is a rule of law against the application of an exceptions clause to a particular type of breach.

The law is satisfied if the party placed in a difficult situation by reason of the breach of a duty owed to him has acted reasonably in the adoption of remedial measures and he will not be held disentitled to recover the cost of such measures merely because the party in breach can suggest that other measures less burdensome to him might have been taken.

Then if at any time and for any reason the principal debtor acts or fails to act as required by his contract, he not only breaks his own contract but he also puts the guarantor in breach of his contract of guarantee. Then the creditor can sue the guarantor, not for the unpaid instalment but for damages.
