''… exercising a right of appeal against what is said to be a seriously unfair disciplinary decision is not likely to be treated as an unequivocal affirmation of the contract.'
''… if the employee exercises his right of appeal under the contract and does not withdraw the appeal before its conclusion, it is obvious on an objective basis that he is seeking to be restored to his employment and is asking and agreeing (if successful) to be treated as continuing to be employed under his contract of employment for the interim period since his previous dismissal and continuing into the future, so that that dismissal is treated as having no effect. It is not a reasonable or correct interpretation of the term conferring a right of appeal that a successful appeal results in the employee having an option whether to return to work or not.'
