The instruments identified, which were subsequently the subject of implementation agreements, are: ■ solidarity contracts for a period of two years with a commitment to extend it for a further twelve months, in order to allow redundancies to be minimised over the three-year period, particularly through early and voluntary retirement using the other legal tools identified; ■ support for early retirement using the voluntary redundancy tool; ■ recourse to article receiving an amount equal to the pension accrued until that date (so called early retirement paid for by the Company).
