"...By their employee Mr Murray on11th January 1988 , and by their letter dated14th January 1988 , they gave me notice to terminate that employment. At the date of termination, I was employed under a contract where ordinarily I worked in Great Britain.
"The unanimous decision of the Tribunal is that it has jurisdiction to hear Dr Pang's complaint underS.54 of the Employment Protection (Consolidation) Act 1978 , and Dr Pang is not excluded therefrom by either S.141(2) or S.64 (1)."
"THE TRIBUNAL ORDERS that the appeal be allowed and the matter be remitted to a differently constituted Industrial Tribunal on the question of jurisdiction in the light of the judgment of the Employment Appeal Tribunal
"All these provisions are consistent with the continuance of Dr Pang's contract of employment with Glaxo Operations UK Ltd and inconsistent with its termination. Mrs Oliver (she was appearing for Glaxo Holdings at that stage) contends that it is not possible for an employee to have more than one contract of employment, with different parties. However we do not think that, in any event, anybody can go further than to say that this ought not to happen. We think that in this case it did happen. This may have created some anomalies, but there would be many more anomalies, in all the circumstances if the two contracts of employment, that with Glaxo Operations UK Ltd and with Glaxo Hong Kong Ltd, did not co-exist after April 1987."
"As already indicated, we agree with that conclusion and we think that there are several factors that point in favour of this, including, of course, the one which has been identified by the Industrial Tribunal, namely, that the events in 1988 are scarcely explicable save on the footing that there was residual existence, to put it no higher, in the English Contract of Employment with Glaxo Operations UK Ltd. There are other reasons, too. It seems to us that Dr Pang must have continued to be under continuing obligations to Glaxo Operations UK Ltd, for example, the obligation to his employer not to divulge confidential information, on the footing that he remained employed by them rather than on the footing that he was an ex-employee of theirs. There are significant differences between the two.
"That, in our judgment, inevitably focuses attention on the position that governed Dr Pang at that date when his contract or contracts were prospectively brought to an end by the notices that were served in that single letter of4th December 1987 . It is, in our view, to that contractual situation that one has to consider whether S.141(2) applies and it follows from that analysis, if it is correct, that it is an irrelevance to consider the place and terms of Dr Pang's subsequent activities pursuant to his discussions with Mr Murray and a letter that was written to him on14th January 1988 ."
"Following your recent discussions with Mr Maidment, I set out below terms and conditions on which it is proposed to amend your existing Contract of Employment."
"Except for the above amendments, the terms and conditions of the Contract of Employment will remain in full force and effect.
"I accepted this breach of contract as the effective termination of my employment, and exercised my right to leave within the period of notice."
"27 Now looking at the history of the applicant's employment with the respondents, the reality of the matter is that he was changing fundamentally the basis of his employment with the respondents so that from working in fact inside Great Britain under a contract of employment which clearly involved working inside Great Britain he was taking the more adventuresome path going to Hong Kong to implement project China. His whole future with the respondents changed. His contract with the respondents was varied to take accord of this change. Things did not work out and unfortunately for the applicant his employment came to an end. However from when he went to Hong Kong up to his return after4 December 1987 he had worked out there under his contract and his contract, that is his contract with the respondents and not just the Hong Kong contract had been varied to take account of implementation of acceptance of a post as Project Manager - China.
"17 We have then considered what is the contract of employment? As I have said from the judgment of the Employment Appeal Tribunal, it follows that the contract of employment we are considering is the one with the respondent company, or Glaxo Operations UK Limited; (UK Contract), it matters not, as amended to accommodate (which is the word used in the judgment) the contract with Glaxo Hong Kong Limited (Hong Kong contract)."
"Miss Downing submits that Dr Pang is entitled to rely on the period when he worked for the respondents at Ware from18 January 1988 to25 March 1988 , as a period when he was employed in this country by a United Kingdom company and that, in respect of this period, he is not excluded from the benefit of the Act by section 141(2). ..."
"Whatever else can be said about this case, Dr Pang was undoubtedly employed by Glaxo Operations UK Limited or Glaxo Holdings Plc (or both), working at Ware in the United Kingdom, from18 January 1988 until25 March 1988 . That being so, we agree with Miss Downing that section 141(2) does not apply to this period of employment."
