I called OSHA

So long story sotrt, I called OSHA on my store, they came in and damn near shut our store down completely. 1 manager got wind that it was me that called and is now pushing to get me fired. (Given I did just accidentally cause a saftey issue to a point they can fire me but they already put me me a final. He took it above the store manager to corporate to have them review it.) I'm at store in Arkansas. I'm not sure what I should do. Our store was fined by osha.

Edit: OSHA legitimately almost shut our store down due to their findings when they came and walked. AlsobI made the call way back in April. So this is not a new call. But management found out I'm the one who called.
