"I write with reference to your ongoing incapacity for work. You have been unable to work since10 November 2004 due to the suspension of your LGV driving licence due to heart problems. You have now informed us that you are due to have a pace-maker fitted, which will mean that you will be unable to drive for an additional six months following this procedure. As a consequence of this we have made the decision to terminate your employment with effect from today on the grounds that your contract of employment has become "frustrated"
"The doctrine of frustration of contract has been implied in the employment law area from time to time. But where a frustrating event occurs the contract in question terminates automatically, without either party to the contract bringing it to an end. In this case it was abundantly clear that, whilst the language of frustration of contract was used, the Respondent terminated the Claimant's contract of employment and thereby dismissed him."
