Over simplified
parabellum :
I think that you are over simplifying this issue.
It is not simply that we did not see this coming. Rather it is that it has been forced on us with NO compensation. To make matters worse we are being forced to accept this on lesser terms than our current contracts. To be clear we are being asked to take a pay cut, give up three weeks salary, in order to work to 65.
The end result is that most FO/SOs will have to work for free for several years after 55 in order to get back the pay that has been taken.
If you had planned to retire at 55 then you are loosing an enormous amount of money.
If any of this had been addressed then maybe you would have a point. However since you did not work here, and have no idea of the negative impact this has had on the junior crew (including Captains now stuck in Hong Kong until the end of their career), I would suggest that you are not adding anything of value to this discussion.
Cheers
Enjoy your retirement.
