Just out of curiosity, since Chap brought up an interesting point...
How many of you have worked for a union before? Or had your spouse/signficant other work for one?
I don't find it all that interesting either, particularly in light of the fact that it is likely that his wife had a pension in the first place because she was in a unionized work environment. He seems to think that she had a pension out of the good graces of her employer and that nasty union took it away when the more likely scenario is that the union got her the pension in the first place and management decided it was unsustainable and insisted upon no pensions for new workers and the classification system to determine who is and who is not a new worker. In short, I understand why he is pissed, I'm just not so sure he is pissed at the right people.
Now, if the union has failed to represent his wife's interest properly and she followed the union contract for grievance purposes and the proper procedures were not followed, that's a legitimate beef and there are means to go about rectifying that.
To answer the question, I'm not in a union and neither is my wife but we both grew up in union households (UAW, IBEW, respectively).
