Sexual harassment is not an ethics issue - it is a legal issue.
Have you read my company's publication on what type of matters can be reported to the hotline? In face, in our "sensitivity" training, calling the hotline was a specific option we were instructed to use if we didn't feel we could go to our managers.
In order to do an effective investigation HR needs to interview you and any witnesses; they cannot do that if you hide behind the ethics line.
Uh, they can interview all of the people in the manager's work area. That would be normal. At other companies, I've been interviewed as part of investigations about other people that were a result of a hotline report.
ALSO HR OR ANYONE INVESTIGATING HAS THE ABILITY TO ASK ME ANY QUESTIONS THEY WANT THROUGH THE HOTLINE. They also have the ability to encourage me to come forward via the hotline if they are so inclined. Apparently they are not inclined. I can bet on what happend. They talked to this guy and he bullshitted his way out of it. They probably talked to his boss who poo-pooh'd it; after all, they're buddies.
You complain that they've been ineffective before; well, maybe that's because you're tying their hands.
Uh, have you asked me any questions about what I mean by their reputation of incompetence. Just how, Mr. cbg, have I tied their hands on any matters in the past?
