All of this.
I’m staunchly pro-union. My wife works in management for a large privately owned manufacturing company that is highly unionized. On the whole, labor relations are good because each side respects each other and understands that there is give and take on both sides. It helps that the company is very closely held (one family owns the entire company) so they’re not beholden to external shareholders. It also doesn’t hurt that the company extends a fair chunk of the union benefits, i.e. healthcare, pension, vacation, to management which makes management happy.
This is all a long way of saying that there’s a way for unions and management to work together and not have an adversarial relationship, but that requires good faith on both sides. In this case, it appears that neither was negotiating in good faith although I will give credit to USMX for making a significant move off their position last night. On the other side, you have a union president acting like a mob boss and giving a masterclass in how to get public opinion against you. His constituents have a very strong case for increases in wages and retirement, but he’s lost the message when he threatens Americans who are already skittish about the price of everything. If I was represented by the ILA, I would be pissed.
