I have never figured out why it's in a unions best interest to protect the lousy employees of the world. What does it get them? Nothing but bad press.
If anything, unions should be the ones promoting better behavior on the part of their members. They should be the ones drumming the worst of the worst out of the unions, not fighting employers trying (and failing) to get rid of bad employees. They have their lame marketing motto, "look for the union label".
Why would I look for the union label?
If anything, I am looking for the label, so I can avoid it.
