My place of employment had a discussion on this matter.
Should everyone be required to get the vaccine?
The answer was no, it doesn't make sense. And i live/work in a VERY liberal City.
There are many of us working in the office and in the field, some vaccinate, some not.
They told me because i travel a lot that i "should" get the vaccine.
I told them the choice is mine and not to ask me again.
Everything is fine. I've been all over the US over the past year, dozens of flights and travel destinations. Hotels, restaurants, bars, doc offices, client offices, job sites, etc.
