If all that is alleged in RBs posting and the disciplinary procedures have been circumvented, modified or dispensed with just to union bust, then we will see a series of Employment Tribunals dishing out pots of compensation to those who have been dealt with in this manner.
The problem with postings on any website is that the level of proof that is required in them is very low. RB makes many allegations in his post and asserts many things, but it is the nature of this type of post that there is nothing in the way of verifiable evidence. It is all just someone's opinion.
The purpose of this posting is to preach to the choir; the intended audience already believes that BA is behaving in an underhand fashion and there is some shadowy within house organisation that is being used to union bust. The level of examination to which RBs words will be placed is minimal, as its veracity is irrelevant except where it serves to bolster up support. It helps the die-hard to "keep the faith". The problem with faith is that it relies on unprovable things - prove that God exists, you cannot, you need faith.
Without wishing entirely to dismiss this as all untrue, it does reek of the the sort of posting that you see on any conspiracy nut website. It is long on accusation and short on hard evidence, evidence that would stand up in a court of law, where hearsay and innuendo do not make a case. I await the legal cases with anticipation, after all if this is all true then we can expect to see BA losing lots and lots of ETs in the near future and paying out much compensation.
