I really believe we ought NOT to have vaccine mandates..., highly encourage, yes, but not mandates.
Our stance really ought to be consistent. I think I've stated before that I'm both pro-life AND pro-choice. Pro-life as to highly encourage life... which is try our best to save the babies... and try our best to get vaccinated... However, if people for whatever reasons choose something else when it comes to their personal medical care, governments ought to respect people's choice. Every life/situation is unique, governments should not impose one size fits all mandates.
Lastly, you probably don't want to piss your truck drivers off. Surely we've all heard of supply issues?
