I'll just take the first so-called example of a "threat":
"Aside from the above mentioned event, there have also been other discipline events like not using reflective vest for walk around, one pilot dismissed from the company for failing alcohol breath test, improper language on ATC frequency and pilots missing flight assignments.
Therefore are you saying that if you were in charge of operations, that such events are actually not "discipline events", and/or such things are otherwise quite acceptable occurences?
You mean you would not sack someone for failing an alcohol breath test?
