I call in the entire coaching and office staff and express appreciation for a first year job well done with hefty bonuses and raises. Increase responsibilities with new titles too. Share the excitement for what's coming in year 2, and sell the idea that this is going to be a great place to be now and going forward. Appeal to their pride and ownership of their passion for seeing the job through to completion (whatever that may be). Etc., etc.
Of course, wish them well with any opportunities outside the organization but encourage them to be patient and seek a good opportunity. Don't be desperate and don't let it be about the dollars cause we will do what we can to keep you here.
If Jerry Jones can keep his assistants by paying them through the nose, despite his meddling, I'd like to think Schoene, and Mara, could do likewise but better.
