Victor 2, you obviously haven't read what Joe wrote. The only safety related part in it referred to the removal of the seniority system to be replaced by "merit".
What followed then was purely Joe's personal opinion, backed up by many professional pilots no doubt, that the removal of a seniority system for promotion discourages speaking out.
Joe's piece WAS industrial, which makes it so brave.
We have to ask ourselves as a profession and as a country; do we allow free speech or not?
AIPA have said they would take this to the High Court if necessary. In the mean time Joe will need to be supported.
