It most certainly is about individual liberty. Doing it in a twisted way, making someone else mandate it, still effects your individual liberty.
All the ‘young’ folks have been conditioned by ‘government’ education to believe the government can do anything to you it wants to, and the non-elected governmental bodies too.
This is fundamental individual liberty. Your body and right to work and move freely.
I deal with OSHA mandates all the time. Show up on a construction site without a hard hat in my industry and you'll deal with both OSHA and the contractor's insurance carrier.
Let's all be honest here. It's the nature of this OSHA mandate that's really made it unacceptable, not the legality of OSHA mandates.
I'm surprised nobody has raised the most obvious point here in this legal proceeding: Using an OSHA Emergency Temporary Standard to impose permanent conditions on workers is an outrageous abuse of ANY government power.
