Yeah, for sure. Probably seems like a better idea to me, based on the assumption I wouldn't ever have to manage the sup res contact list!
But we do have pretty good luck with some of the DND PS retiring then coming back on that contract doing 90 days a year (can't recall the name), which works pretty well for special projects, or when we don't actually plan to have a turnover then panic 6 weeks after someone retires because we just lost 40 years of niche experience and realize no one has any idea how to do that job.
