The system set-up will likely be binary. Either they will expect us to agree enthusiastically to the vaccines or be hesitant/strongly opposed. They wont expect people to short-circuit the process by, for example, making multiple appointments and not showing up.
Someone on another forum suggested we do with this vaccine what he has done for years with flu vaccines (which are mandatory for his job). He shows up, signs all the necessary papers and then walks out before getting it. That way he has documents 'proving' he's had the jab which he then show to his employer. Hilarious
Not sure if you have to provide written consent for the Covid jab, if you don't that's criminal, but it might be interesting to go along with it right up until the last minute and then 'change your mind'.
I plan on doing some of this myself. If I do I'll keep this forum updated.
