I have been vaccinated. Not tested. No. Therein lies the problem. You can pass it on before you know you have it.

If you know you are regularly exposed to it, I think it is your responsibility to get tested regularly. If you're regularly exposed to it due to your job, your employer should be providing those tests.
You should be doing whatever any reasonable person would do to protect yourself and others. The vast majority of the population is not regularly exposed to it and not high risk. If they are vaccinated, I have no problem with them not wearing a mask. Even if they aren't vaccinated, I have no problem with them not wearing a mask.
Vaccination is not a guarantee you won't get it or spread it. Not being high risk isn't a guarantee you won't get it or spread it. Neither is wearing a mask or social distancing. All of those things simply make it less likely. It is up to you to be a reasonable person and do what you think is appropriate based on you lifestyle and risk level. You don't know what those are for other people, so you shouldn't try to impose that decision on them. You do you.
