Well, if you can avoid it, I wouldn't recommend full-on unemployment unless the situation is really that bad. Work provides an intrinsic sense of daily purpose and routine that does help with psychological recovery, regardless of how one feels about it in the middle of burnout.

A part-time schedule could always be part of the burnout plan. Or a planned sabbatical. Like I said, do the creative thinking now so it's not when you're in the firefight.
