Husband Outed for Mental Health Struggles by HR rep

Location: Indiana

Wondering if we have recourse here and would appreciate some advice. We've never had to do this before. Sorry for the long-winded post and hope I chose the right flair.

My husband currently works in an automotive factory and about a month ago, he confided in me that he was struggling with mental health issues (anxiety and major depressive disorder) and that he was having thoughts about harming himself. Got evaluated, came up with a safety plan, then discharged us. We've since adjusted his meds and he is doing much better, but he asked to be written off for a few days so we could get with his therapist and doctor. When he returned to work, the HR rep he had originally been dealing with and knew the situation was there. He went to take his documentation to her and she rolled her eyes and said something to the effect of "Oh yeah. Heard you were gone". She scanned over everything and said, "Well, I don't know if we can accept this. It doesn't say the doctor wrote you off. It said you made the decision, not the doctor." My husband then said, "Call, Other HR Rep, she knows about everything and cleared it." The woman rolled her eyes again and when my husband asked if was cleared to go back to work and she went, "Yeah, I guess, whatever."

Fast forward to lunchtime. My husband is eating lunch and someone stops him and says, "Hey, buddy. You doing okay? Did you get your crazy pills?" Later, another person said they were glad he was getting help. He said people were making comments to him the rest of the shift. He called me on his last break and sounded so beaten down. For reference, he's also a brittle Type I diabetic and has other illnesses that have negatively affected his attendance. He always has legit doctors notes, but the multi-million dollar facility needs to make money and we get that. The only people at the factory that knew about his mental health struggles are the two HR reps. My husband has recently been trying to talk to his team leads about how to go about asking for help or a meeting and they won't address him.

What are our options here?
