Companies have a right to protect themselves from outside and within, your job to them is a privilege, the Union is siding with the CDC and Federal Mandates, they get their agenda passed with the Federal side, who they gonna side with Trump? Oh that's right he and his whole family and administration got vaccinated also all the while telling his supporters it was fake, a hoax, drink bleach, take unproven medicines.
The science has shown a large difference in symptoms, transmission rates and recovery of those vaccinated and not vaccinated.
The people that are vaccinated have rights also, to not have to feel they are in a petri dish with those that would rather roll the dice and hope they don't get infected and infect them with a new variant.
