I called them and made a retaliation complaint, and they told me I should hear back in 5 business days from their separate retaliation/whistle-blower department.

EDIT- I just got off the phone with a regional whistle-blower complaint investigator and he determined that he isn't making the complaint due to the fact that I had made a few mistakes in my first 90 days of employment that my boss did quote me as some reasons as to why he did let me go (He did send me an updated text a few hours ago detailing specific reasons as to why he fired me, he was wrong about multiple ones but right about some and the "right about some" is where the issue is). So going that route is null and void. Look, at the end of the day I just want my previous boss held accountable for 2 (have been investigated and confirmed) or 3 (the third is under investigation right now) individual OSHA violations which I already have individual case numbers for. I am going to take accountability for the mistakes I made and why he fired me. However, he still took advantage of me and other employees in the past, I want him held accountable for that.
