Rumour was at DHL they(balpa) did a ballot to decide who the workforce wanted to represent them, but only balloted the Balpa members.
The fact also remains that some people will be members of both unions and a simple membership majority in terms of baby pilot mumbers may not indicate that, that many actually want IPA to take over, based on the strike ballot 3/4 years ago Balpa aren't exactly switched on when it comes to ballots.
Although IPA membership is 50%+, is the figure the same registered on the IPA babypilot group website asking if you would support the change?
Only way that everyone will be convinced it is representitve of the whole workforces view is if, in my opinion, the company does the ballot.
