In my day the reporting went both ways. Pursers and SFS's - many of whom knew no other career or more professional work environment - felt perfectly justified in bullying and haranguing junior crew on SEP, service procedures, first aid and whatever. There's a culture of report-writing and snitching that starts in training college and carries on through (2007 Perth incident anyone?).
Now I don"t know the circumstances here in any more detail, but sometimes junior crew feel justified in getting their own back. It's ugly, but that's what the culture of the office and the briefing room is.
