I know crew literally too frightened to leave their rooms down route in case they get into a row with flight deck or VCC.
I have just flown with a CSD who is frightened to go out with cabin crew because she was a non-striker. Consequently she stays in her room, is lonely and has been reduced to tears on several occasions by deliberate and spiteful acts on the aircraft designed to undermine her authority. She has asked to downgrade her status to purser where she will be less of a target but this has been refused. She is very stressed, now dreads going in to work and is contemplating leaving the company after 21 years. At work she appears cheerful hard working and a pleasure to work with. What a waste.
