In voting for an "employer justified retirement age" (EJRA), the academics have decided that, upon reaching 67, they must either take their pension or reapply to stay at the University. Claire Churchard, writing in People Management, quotes Indi Seehra, HR director at the university as saying:
Introducing the EJRA for academics will support intergenerational fairness. It will allow our academics to progress through the promotional stages in the course of their career and help to create a balanced distribution of ages.Sources: People Management "Cambridge academics approve compulsory retirement age" (May 3, 2012); The Cambridge Student "Analysis: Should Cambridge dons be made to retire at 67?"

In an environment where innovation is needed, you need new people to come in to the cohort to create innovation. But you need the capacity to allow them in, and if you haven’t got people leaving then that will be a restriction on the capacity for new people.
