There could possibly be a case made for Worker's Compensation if these jabs are given on company property. But you are right. If the employer is told by the employee that the employer will be held financially liable for any and all damages that the employee suffers because of the being required to submit to medical experimentation as a condition of employment, they just may think twice and back down when they realize that not only could they be financially on the hook, but they could also be criminally prosecuted. We must stand our ground.
