If its the law of the land how can mandatory retirement still be legal?
It's legal only if the case can be made that it's required. ACPA and Air Canada didn't make that case...ergo it's illegal.
Do you have any reason to believe this won't be in the courts for years?
Yes.
I have to admit that I'm puzzled why someone as junior as you claim to be supports this so wholeheartedly.
Several reasons. First of all because I believe it's discriminatory to force someone out of their job for the sole reason they had a birthday. Secondly because I am capable of thinking beyond my own immediate future. There are more reasons but they are the biggest.
This will do nothing but penalize the junior ranks..
False. You will realize that when you get older and see how this benefits you and every other pilot. Not to mention every other working person in this country. If you want to lay blame on someone for any negative effect this has on you, look to ACPA and yourself. You didn't insist ACPA prepare for this and so they didn't.
Senior guys benefit, junior guys get hung out to dry again..
You have not been hung out to dry. Don't believe a fraction of the bs ACPA has put forward justifying this.
