As far as attrition rate goes, I have been keeping it very simple. I started watching a certain DEFO on 15 April. They have moved forward 54 places in 4 months.
Over the year that equates to 162 people leaving. More like 5% rather than the DFO's quoted 3,5%. I suspect that they don't include the early "retirements" in the numbers.
If we ran an airline and not a circus most of the early retirees would have worked until 65.
