Sadly I don't think there's any point comparing BALPA with the likes of the docs or RMT, and saying we should just "man up'
As I understand things in the UK the medics have major control over the supply of chain - via the Colleges, to a single organisation ( the NHS)something BALPA doesn't have, and The RMT has the monopoly on the supply of labour to the London Underground. in both cases the IR situation is very different to ours where we have a range of pilot groups with their own industrial agreements with a multitude of companies.
FWIW I agree that the OPs gripe should be be with his/her CC, not the Union
as a whole.
