PC767,
What you've posted from the BASSA forum isn't, sadly, what they've sent out in the letter dated the 9th Jun to all Unite cabin crew members. Their third point of issue for ballot is as follows and doesn't mention the word unwarranted
3. We consider the disciplinary action taken against Unite members for various misdemeanors (sic) related to the current industrial dispute as vindictive, disproportionate and unnecessary. Unite is therefore seeking the withdrawal of all disciplinary measures administered to Unite members under those circumstances discussed during the recent negotiations.
And that's their official pre-ballot communications.
MrB
