Effective the end of summer. We've got an unexpected search committee trying to find a temporary fill-in, and another, longer-term, is to begin work in Fall. We're waiting to hear from the Dean just how many positions we'll be able to go after - there are also a couple of retirements coming up, and they'll need to be replaced as well. It's a headache. (Fortunately, the areas that need filling aren't ones I'm qualified to evaluate, so I won't be on the committees...)
