Was talking to a "union" rep who said they were not able to talk to us and suggested looking up the word strike in google
Not able to talk to us ?? Under who's instruction ?
If that is what you were directly told then I would personally be on the blower to the head of the Union (name & number available via unite website) asking if they have instructed that reps no longer speak to crew.
If they are not aware of this advise him of the individuals name and exactly what she/he told you (there is an outside chance the management/company are telling reps this which is questionable in the least).
If they are aware of it ask why this has happened and request a formal communication to members to advise this.
We pay our fees such that we can speak to and ask advice of the reps at ANY time. Get on the blower and escalate it.
