This is about age discrimination. The Minister of State is going through this rapidly and I am trying to absorb the rationale. His last comments seem to suggest there could be discrimination. Fixed-term contracts seem to be a way of terminating the employment of somebody over the compulsory retirement age. The amendment reads: "...it is objectively and reasonably justified by a legitimate aim". Will the Minister of State clarify what this means? The amendment also reads: "...the means of achieving that aim are appropriate and necessary". What does this mean in simple English?
