Ohhh men, It's turning into another KLM UK debate.
Anyways here is the text from the BOM
Either the English or the Dutch language may be used as the common language for communication on the flight deck and between crewmembers during line operations. When crew composition so dictates the English language shall be used
BOM 8.3.1.1
The case you talk about is of one specific individual, well known in the entire company for being a giant a$$hole, he refused to fly with one ex UK guy that you forget to mention is also known for being extremely lazy. Nevertheless the captain in case got into more trouble that the UK guy and as a result the BOM was CHANGED. You forgot to mention that.
Further more, If you read my posts in the past, you know I didnt agree with the KLM UK situation, but can you give me an example of any former UK guys getting hired with AF, IB, LH or AZ or even BA
I would still like to see any specific reference to the article in the CLA where it states that new hires have to be fluent in, what did you call it, BI european dutch standard.
