So tell me how sacking people who still won't get the vaccine after they've been sacked and who then keep on going out into the big wide world is going to make that big wide world safer. It might make your workplace safer (or it might not) but you will have solved nothing in the wider scheme of things. I can see a case for being stricter with people who work with the vulnerable. Otherwise, try to remember that we live in a democracy, and, generally speaking, democracies don't try to force people to have needles stuck in them. Always persuasion, never compulsion. Information and education are the way to get doubters to agree to be vaccinated. We don't do very well with that, do we, preferring to let Facebook make gazillions    and completely neglect their social responsibilities via the peddling of conspiracy theories and downright lies by its members.
