I used to get answers and help here that I could not get at my building. And from what I hear, there is literally no HR anymore. And how can you be on the phone getting answers when you work from 9 to whatever? Pension help is best through email. Medical benefits help..is a toss up. Takes time on phone. And they are there from 9 to 5, so you use a break and are on hold and there goes your break and no answer.
As for termination, you will get far more opinions here than from your steward, or union. Yes the local is important, but this is a wider forum than your local. I was never terminated, but if I had been where would be better to ask about if anyone else ever experienced? Too much knowledge is never bad when your butt is on the line. Some of us, you old timers do not remember what it was like to be new.
