Actually, very well said lowerlobe and Stubby Jumbo....both providing salient comment and in the case of LL sound advice.
The FAAA has just issued a news letter that deals with this very subject as a warning to crew being "iterrogated" by the CCTM's.
Disciplinaries – “Clause 11’s”
Crew would be aware that after continued pressure and outrage from both the FAAA and crew themselves, the Company has resorted back to more informal methods of dealing with incidents involving crew.
However, we still have major concerns regarding the way that crew management is seeking to “manage” crew. The approach of individual managers is often inconsistent and piecemeal. We will be meeting with the Company to further address these issues and our concerns about the clause 11 process generally.
We also have serious concerns regarding the conduct of the “clause 11” formal disciplinary proceedings by crew management. If you are asked to report back to the Company regarding any incident, please do not hesitate to contact the Association for advice. You may be giving a manager just an update regarding a flight. Or you may potentially be an important witness to an event that could have major impacts on a crew member – the disciplinary outcome could cost them their job. Never sign a document without reading it carefully and fully agreeing with the content – you will have no control over where this document goes or how it will be used. Don’t just sign it as you are about to sign on or off. Think about the implications of your actions.
Even if the incident involves a member of the Association (as they mostly do), you can seek confidential advice from the Association. The Association uses the practice of “Chinese walls” where individual members can seek confidential advice from another official, even though the Association may be representing other individuals involved in the same incident. The advice given will best represent your interests.
