"The submissions to the Tribunal centred on the questions whether the respondents had a right to vary the arrangements contained in the agreement referred to at paragraph 6 above, and whether the changes which they effected unilaterally were truly material changes to the applicants' contracts of employment. The legal argument centred around the decision of the EAT in Hogg v Dover College . Was there a termination of the contracts of employment under which the applicants worked followed by a substitution of new terms and conditions? Was there a direct dismissal under the terms ofSection 55(2)(a) of the Employment Protection (Consolidation) Act 1978 or a constructive dismissal of the applicants by virtue of Section 55(2)(c)?"
"The 1988 agreement makes an essential distinction between the shift pattern upon which the applicants were working and the rolling shift pattern which such other departments as the security department worked. The two were never contemplated as being one and the same. There was an essential distinction between them."
"I conclude that the applicants' former contracts of employment providing for employment in jobs with a steady and predictable pattern of shift employment were removed from them and replaced by an altogether more demanding and previously uncontemplated regime of rolling shift pattern work which the applicants were certainly not obliged to undertake by their contracts of employment. I unhesitatingly adopt the part of the judgment of Garland J set out at paragraph 23 above."
"Paragraph 5(2)(a) deals with cases where the employer himself terminates the contract by dismissing the man with or without notice. That is, when the employer says to the man: `You must go'. Paragraph 5(2)(c) deals with the cases where the employee himself terminates the contract by saying: `I can't stand it any longer. I want my cards.'"
"For my part, I can see no reason in law or logic why, leaving aside for the moment the extreme case of outright dismissal or walk-out, a contract of employment should be on any different footing from any other contract as regards the principle that `an unaccepted repudiation is a thing writ in water and of no value to anybody': per Asquith LJ in Howard v Pickford Truck Co. Ltd 1951] 1 KB 417, 421."
"I conclude that the applicants' former contracts of employment providing for employment in jobs with a steady and predictable pattern of shift employment were removed from them and replaced by an altogether more demanding and previously uncontemplated regime of rolling shift pattern work which the applicants were certainly not obliged to undertake by their contracts of employment."
