It's not about being their enemy, usually when there is a merger the surviving company union and benefits become the norm.If those two things are not going to survive the JCBA, because the American guys will not have those two items to begin with, then you use those two items Medical and the pension to gain stuff for the good of the group. Like if you can gain more work in house, you gained something for the group. Don't just give it away, even though you know it will be gone, get something for it.
