The Inspector General of the IRS was the one asking these questions. First, I don’t believe he has the authority to compel testimony, ie, answer or be fired. Second, a low level agent would be stupid to answer the IG in the first place. You’re asking him to rat out his boss or bosses boss. He’s got to have more cover than the IG can provide.
The Org. Chart will identify them.
I think the union rep was in the office when the employees were questioned. Two years of investigation by the IG and nothing was accomplished or determined. IG Investigator needs to be fired!
The rules are probably different in the private sector.
