The Department does not have a separate category of staff on “gardening leave”, as those without permanent posts are actively managed by their line management and where possible deployed on temporary work. There will be occasions when such temporary work isn't available, but that situation is continuously changing and is not recorded centrally. It would cost around £2,000 to survey all relevant management areas to estimate the level of such “gardening leave” at a point in time, and substantially more to monitor it continuously.
