In Indiana, is it legal for a company to fire an employee without informing him or her for months? A course of action was dictated by the Union Local and the employee followed through faithfully for 7 months. Meanwhile, the Union had withdrawn the grievan

Union worker, 10 years of service, transferred to another plant (and another local) when department closed down. 3 months after arriving at new plant, was suspended by the company and targeted for termination.
Was told by the Grievance Chairman at the new local to attend Employee Assistance Program while the matter went to the next step in the grievance process. Did this faithfully for 7 months.
A mishap with medical insurance (they didn't want to pay) alerted me to a problem. After repeated attempts to contact the union hall, I was finally contacted by a lower level Griever, who could only tell me that the grievance filed on my behalf in September had been withdrawn in January. He also said for clarification purposes, I'd have to contact the Grievance Chairman, who's apparently been dodging me.
Insurance was cut off in April but up until then, I had no of knowing I was on the sacrificial chopping block.
The company dropped the ball, as far as notifying me -- or the union did. Instead of dodging me, I feel they should at least pretend they're more concerned about union members than covering somebody's tail.
So my question comes in two parts.
#1 Is it legal for the company to terminate in Indiana without notification? (I still haven't got a call or any other correspondence.)
#2 Is there a reason the union local would fail to provide fair representation, other than political BS between the local and the one I transferred from?
I realize this is a complicated question but I would appreciate an answer sometime.
Clearly there has been an abuse of power somewhere in the mix and if employees can have their feet held to the fire, why can't companies and incompetent union locals?
Thank you in advance for any thought you give to this matter.
