The expectation as to when a university faculty member would be informed of a sexual misconduct allegation against them would be immediately. The reason is because the school is concerned about its liabilities. If a allegation of sexual misconduct is made against a university faculty member, the school is concerned that they could be on the hook for whatever alleged misconduct the university faculty member is alleged to have done.
For that reason, the school would put the university faculty member on notice that there's an issue, a major issue. Unfortunately, schools hold students to a high standard of accountability when it comes to allegations of sexual misconduct. They hold university faculty members to higher standards, yet, university faculty members also are, unfortunately, more likely to be subject to interim measures that would include a temporary suspension of their employment.
Schools have tended to shy away from that with respect to students, but in the case of university faculty members, they still very much, not in all instances, but in respectable numbers do impose interim measures such as temporary suspensions of their employment duties, which can unfortunately due to the length of some college sexual misconduct cases lasts for a respectable length of time, obviously, impacting the university faculty members, say, teaching, assignments, and so forth.
An experienced attorney advisor can help protect a university faculty member's interest throughout the process and should be involved from day one.
