gong,
I don't disagree with your principals and ethics. just calling it as it is.
A place that is finding it hard to recruit crew will continue to do so unless the small items, such as pay, bonding and other such things mentioned are fixed to entice professionals to join.
Without a representative body to deal with these issues, such actions taken (being unprofessional), cast light on certain areas.
The reaction to further bond (if that is true) an upgrade candidate as a result of the resignation gives you an insight, react now think later method, which is detrimental to the encouragement of good crew applying for an upgrade.
Its a 2 way street.
