This case concerned the alleged contravention of existing agreements in regard to the implementation of increased working time. The relevant provision stated that additional hours agreed would not apply to “IMPACT grades up to and including Grave VII and equivalents”. The dispute focussed on the meaning of the term ‘equivalent’. Based on the evidence it was clear that the terms and conditions of the complainants’ grades were nearly identical to those of Grade VII, except the maximum point of the pay scale was exceeded by €188 per annum. Accordingly, the Court held that this was an insufficient amount to justify classification as any other grade.
