What may be reported with REPCON?
Any matter may be reported if it endangers, or could endanger the safety of an aircraft. These matters are reportable safety concerns.
Examples include:
* unsafe scheduling or rostering of crew; or
* crew or aircraft operator bypassing safety procedures because of commercial pressures; or
* non compliance with rules or procedures.
To avoid doubt, the following matters are not reportable safety concerns and are not guaranteed confidentiality:
* matters showing a serious and imminent threat to a person's health or life
* terrorist acts
* industrial relations matters
* conduct that may constitute a serious crime.
They are not interested in industrial matters, that is, a persons salary and what hoops that person has to jump through to attain same. The only thing you can kick a stink about are those that come under the reportable safety concerns, to repeat,
* unsafe scheduling or rostering of crew; or
* crew or aircraft operator bypassing safety procedures because of commercial pressures; or
* non compliance with rules or procedures
