This Order does not prevent employers from imposing a mandate on their own. Employer mandates may be subject to challenge on different grounds, but that is unaffected by this case.

Rest assured it will open a wave of litigation against the companies doing it.
As soon as one executive goes to prison over it then their own their crusade will cease real quick.
