I don't believe Jetset lady was being unreasonable in her observations. We have all at times complained to individuals when experiencing a few days of "scramble".
She made overservations where she thought improvements could be made and expressed that hope that eventually Cabin Crew would have representation that would actually be able to negotiate on their behalf. Nothing I see that is unreasonable on its face.
Many is the time when an individual will say "I'm exhausted, will I make it through this day" when in reality they are embelishing just a bit to make a point.
I find the fact that there are issues that could be improved to be reasonable...in a large organization there are always procedures that can be improved.
I'm optomistic changes will occur that will make progress possible.
