This issue about HK based crew and their retirement age, not their pay, has been going on a lot longer than this industrial dispute.
It has absolutely nothing to do with Len McClusky who has nothing to do with the day to day running of Bassa and is only involved now because of the strike.
Unite/Bassa/Amicus have a duty to represent all their members and that includes any international crew who are members and this is something that they felt was unfair to them. It is perfectly normal and right that their union represents their views too and tests this in the courts.
I just can't see why any of you have a problem with this.
