re: mandates. here is my thinking:
Private businesses should be able to have mandates legally. Should they do that? Businesses with a lot of low-level personnel, like hotels, should first do small-scale incentives: pay for vaccination, make non-vaxxed pay for weekly tests, transfer them to positions were they don’t interact with public. For businesses requiring skilled personnel, I personally would not trust judgment of those who do not vaccinate or mask and will use this as a good excuse to fire them.
Public/medical: should be able to mandate where it is materially affects public safety: nurses, teachers. firefighters may sleep at the fire station unvaxed if they prefer. Again, weekly or twice weekly testing might be enough. Maybe let these teachers teach online and for sure disclose their status to parents, whatever HIPPA says.
In all cases, if it can be shown at some point, or at some location, that being unvaxed does not affect safety anymore (low transmission level, high immunity, mild variant), no mandate required. I would not be hiring them though and so I presume many others for the lack of judgment.
