With respect (in both senses of the word) to those injured on active service, would not a solution to this be to militarize some of the civil service posts in places such as Main Building and DE&S, and apply an abated X Factor to recognise the fact that these personnel are no longer deployable?
On the subject of the long term fat, and unfit, who make no effort to meet the standards, I feel the introduction of a rehabilitation facility at MPA may concentrate their minds somewhat.
