"I was employed as a clerical assistant by Peter C K Chui T/A C K Chui and Co and Eastern Travel Centre from January 1985 to2nd April 1998 .
"There is an implied essential term in every contract of employment that the employer and employee will not, without reasonable cause or excuse act in such a way, so as to undermine the mutual trust and confidence which needs to exist between employer and employee. Such a term existed in the Applicant's contract of employment. The Applicant contended in this case, that the Respondent's conduct in installing a close circuit television camera and microphone in her room, was a breach of this essential term. When we considered the facts which we had found proven, it was clear that prior to the installation of this close circuit television system, there had been a very poor working relationship between the Applicant and the Respondent. For a period of two years or more before the Applicant terminated her employment, the Applicant and the Respondent had not spoken to each other. Having said this it was clear to us, the Respondent had not breached any term of the contract of employment, including the essential term referred to above, since he had installed the close circuit television system in order to make his employees, including the Applicant and his property safe. It had not been installed with the intention to spy upon the Applicant. Furthermore, when she wrote to him to complain about the location of the camera, he complied with her criticism and moved it. We found that in the circumstances, the Respondent had not been guilty of any conduct towards the Applicant which was a breach of an essential term of the contract of employment, going to the root of the contract, which showed that he no longer intended to be bound by one or more of its essential terms. In these circumstances, we found that the Applicant had not been constructively dismissed. We also found that as she had not been dismissed, her complaint of unfair dismissal was not well founded and we therefore dismissed it."
