"23 … the terms and conditions upon which the applicants are and were employed are simply those set out in the 'collective' documents that they already have."
"21 … We were not in a position to imply such a term as a result of 'custom and practice'. It clearly could not be asserted that there was any such practice (of offering on-call work) within the profession of midwifery. The fact that the applicants may have been directed to undertake such work for several years is not inconsistent with the Trust being at liberty not to offer them it. 22 Even if that were not the case, there would clearly be insufficient certainty in any such term. 23 We therefore concluded that the Trust had acted within the terms of the existing contracts of employment of the applicants in directing them in the manner in which they should perform those contracts from September 2000 onwards. It follows that the terms and conditions upon which the applicants are and were employed are simply those set out in the 'collective' documents that they already have."
