No, there isn't. The only thing is that if somebody's on leave of absence, we're aware of the fact that they're going back, and there is a provision in the code that requires that you can't have direct or significant dealings with somebody that you're going to go and work with after you finish your job. In those kinds of cases, we would be particularly vigilant to assist that person to find mechanisms, such as conflict of interest screens, to avoid dealing with somebody they knew they wanted to work with afterwards.
That happens quite frequently; we're consulted when people are about to leave their positions.
