I'm always sceptical of people posting with little or no history on here however exhibiting more than basic knowledge of this industry.
However on the points raised, a current BMIbaby pilot posted giving his/her direct experiences and thoughts of their peers. It is felt that one union hasn't been effective so has switched his support behind another to see if they can do more. They have shown they do believe in collective bargaining to achieve a common goal and are quite entitled to switch their support (we do live in a capitalist democracy after all).
I'm sure the IPA will throw everything at this because the outcome may raise their stock price and kudos among the pilot fraternity.
If nothing else it may make BALPA sit up, realise the perception of its effectiveness is being questioned regularly and change its approach which will ultimately benefit the whole pilot community in the UK.
