Employment – Wrongful dismissal. The employee was dismissed under a term in his contract (the clause) that stipulated that any breach of the customer or employer's security rules would result in his dismissal. He successfully brought proceedings for unfair and wrongful dismissal. The employer appealed. The Employment Appeal Tribunal held, in dismissing the appeal, that the clause only applied to a breach that was serious and wilful or grossly negligent, applying normal principles of employment law. Further, the process by which the employee had been dismissed had been unfair.
