Prawn2king4, then I disagree. You can disagree with the current union stance and want no part of it but that doesn't make you complicit in supporting them by proxy. A great many crew don't belong to Bassa (or have recently resigned), were previously members of CC89 or don't belong to any union.
Past agreements that crew work to were agreed between BA and the unions (there were two, in case you're unaware) - so working to them is as supportive of BA as anything. The current problems arise because of unions' failure to negotiate.
