The problem I had was some of the exemptions. If someone fits the description so well used by TTN above, the I fail to see why they shouldn't be told to do one. The other argument that seems to do the rounds is that of gender fair or gender neutral. All went quiet when (at an EO meeting) I suggested that war/ops are not gender fair so the only reasonable test was a gender neutral one. Alcock vs the Chief Constable of Hampshire springs to mind!
