I like your style Biatch, never let facts get in the way of blaming everyone else for something you don't understand.
Facts
So in short.
The Company was entirely to blame.
The industrial instruments worked exactly as they should have. LH pilots voted on their document without any interference from SH pilots. SH pilots addressed perceived issues in their document without any interference from LH pilots.
End result that nobody particularly happy, which in general usually means about the right outcome.
If you're not happy with the way your union is representing you, get of the couch and onto a committee and have a real say rather than criticising those who give up their own time and work tirelessly for nothing, for your benefit.
