If we are playing the pedantic game then I'm sorry NotLangley but this statement is 100% correct - "2560 members have left BASSA/Unite ..... ".
1557 have stayed with BA and another 1003 have left BA but they have all left BASSA \ Unite.
OK, enough pedantary - with membership down and if BG is correct in "assuming" that most of the non-voters didn't vote because they left the union then numbers are rapidly approaching de-recognition levels.
I think Richard sums it up well and sadly, judging by the postings by MissyM and Moderately Militant (2 x MMs - are they related?), they still seem totally vague and \ or confused in explaining what they are striking about. Lets hope they see sense sooner rather than later.
