I wasn't there, obviously, because I'm not that old. I understand it was part of the negotiations. All changes that have been made to the pension plan--and we have made several changes over the years since its inception--have been ratified in the bargaining process. So they were voted upon by the members when they voted on the collective agreement. The pension is just one aspect of the collective agreement that we seek changes to. When it is changed, it goes through the ratification process.
On February 15th, 2011. See this statement in context.
