What about second chances for persons who have behaved in a sexually inappropriate manner, given that they may still be able to produce something of value in their occupation (... What about employers warning them, rather than terminating them as employees)?

I do not know what Charlie Rose or Matt Lauer may or may not believe, but for discussion, let's assume they are willing to accept responsibility and to conform to expectations about participation in activities aimed at repair of themselves and others. Let us also assume they have access to a program similar to the RESTORE project in Pima County AZ which aims to foster a restorative justice response to sexual assault. As I understand RESTORE, there are supports for victims to minimize re-traumatization. The offender undergoes a rigorous psychosexual evaluation by a forensic examiner. Any agreement that emerges from victim-offender mediation can not call for less than minimum accountability (case manager supervision, therapy, monitoring by a volunteer community board, and community service).

If the preconditions and resources for restorative justice were obtainable, punishment or retribution against the offender by his employer would be of questionable value. That is a BIG IF.
