All I was pointing out is that she will not be receiving the kinds of benefits that a regular faculty member would, since she was not on faculty, just visiting.
On the other hand, visiting professors are considered "faculty". While employed, she would have been considered part of the faculty with the same options of retirement plans, health plans, etc., as opposed to being part of the staff (adminsitrators, secretaries, ets.).
The cost is to the college's reputation. The financial costs are the days lost by all students and faculty because of this nitwit. Indirect costs are all those fixed expenses that go on, whether or not teachers are teaching or students are learning.
More indirect costs are the time spent by law enforcement personnel (plus campus police) on false allegations.
