DH is an ex BA employee. He has also had two appeals on the subject of his dismissal turned down - one of them stating that he does not have the right to: "having been rostered for duty, de-roster himself because he needed to attend to union business." So, he no longer employed by BA and cannot represent BASSA at meetings with BA. As for future appeals - has he any?
If correct, I note that BASSA's re-selection of officers has been postponed by Malone so that Holley can continue his VERY doubtful position. In view of his ridiculous rantings I imagine that members of BASSA would have expected him to do the honorable thing and resign.
He is persona non grata in my view.
