thanks for the informed reply flyburg.
On the pension issue its not the structure of the pension thats the issue, its the fact that the company has stated that the basic KLM bottom of seniority pay would be pensionable, but the "top up pay" to bring us back to our UK salary pay would not. In some cases that would mean that less than half their salary would be pensionable
Lets not forget that this is not a dispute about joining mainline its a dispute that stems from discrimination. Some people are not in a position to accept a mainline contract (those over 56 for example) and they must be protected too in any agreement made for the future.
