I agree, I am not surrendering the RETRO by any means. My fear is that after mediation is exhausted which I think is 18 months (really not too sure), The company might be inclined to give back what they took back two years past contract expiration and a majority of the membership might be inclined to vote yes. By not giving retro coupled with, as you stated, the money we have saved them, RETRO won't have costed them a dime.
Sadly, I expect this action from the company, but I fear the membership might buy it.
