"6 The respondent is a teacher of photography. Throughout her periods of engagement she was employed by the appellant on a series of fixed-term and part-time contracts at one or more of their educational establishments, situated respectively at Guildford, Farnham, and Epsom and latterly only at Epsom and Farnham. At the relevant time the contracts were by the term, or course at the relevant institution and department , and in consequence were intermitted amongst other interruptions by the usual vacations. Nothing would turn on these periods of intermission if the employee were entitled to add each terminal fixed-term contract to its predecessors or successors for the purposes of the calculations. See Ford v Warwickshire County Council[1983] IRLR 126 . But each was a separate contract. None of the 'contracts' (if that be the right description for some fairly imprecise documents) was in any way colourable, improper or designed in any way to defeat the purposes of the Act of 1987 properly construed; either by finding of the Industrial Tribunal (which is unchallengable) or by concession or admission by or on behalf of the respondent (which after hearing argument on the point I believe to have been binding, as was the ultimate view formed by the Court of Appeal) the concurrent contracts were separate from and independent of one another, and though the practice operated so that the obligations under one did not conflict with the obligations under any other in time or place, did not form part of a single composite whole. Had this not been the case and had there been supporting evidence to enable one to conclude that, although expressed in different documents, there was in existence a single implied contract of service or a composite contract contained in the several documents, I might very well have taken a contrary view to that which I am now constrained to express.
"(1) Any week during the whole or part of which an employee's relations with his employer are governed by a contract of employment counts in computing the employee's period of the employment."
