It seems everyone's crazy sometimes and we choose our psychoses unwittingly! :) Your points are a great way to manage our manic moments. Specifically, when defining acceptable behavior, if character, competency and chemistry are well known core values within your company then our crazy moments have a context that make managing conflicts easier. I serve in a church that has a paid staff as well as a volunteer staff. As you might imagine, in a church there's this unwritten expectation for how we're supposed to handle 'crazy'. From an employment perspective we've jokingly, but somewhat seriously said, "We have a responsibility to minister to everyone, not employ them." Believe it or not that sentiment also affects how we work with volunteers. If 'crazy' habitually contradicts character, competency or chemistry then a break in 'employment' may be the best solution.
