For a short time I had the pleasure of working with a small site that treated the union as a partner and not an adversary. On the company side, it was an EH&S manager, not even the EH&S lead, who led annual negotiations with the union. There were disagreements and compromises, but both sides walked away every year feeling benefitted and ready to collaborate for another year.
Well, Corporate can do better than that. They sent in HR to run things this year. Everything is an aggressive conflict. EH&S dude was immediately recruited to a company down the road and left. Cue HR's surprised Pikachu face when all goodwill with the union disappeared overnight and the union is just as ready to play hardball.
I am glad I got to see one example of a company and union working together for mutual benefit. I think there will be vanishingly few situations like this throughout the rest of my career
That wasn't your question though. If a technical jerboa question is what you intended to ask, about 90% of your post didn't need to be included and the question in the title needed to be very different.
As to your edit, I would not recommend PM'ing the user directly; that may be very unwelcome and further breach rules of that community. Personally, I would have asked the mods for a chance to edit my comment and apologize publicly. But with previous history of your self-described "psychosis", if I were the mod I would be skeptical of your motivations.
