The City of New York is not a corporation, and is one of many municipalities that has forced public employees to take the experimental immunotherapy or be fired. For the record, I have taken the experimental immunotherapy, but that has no bearing on the fact that the government should never be allowed to force people to undergo medical procedures, much less experimental ones.
To be pedantic, the City of New York is a municipal corporation. They are allowed to have conditions of continued employment. They cannot force vaccines upon anybody under the threat of jail time but they can certainly not continue to employ anybody they don't want to. NY is a right to work state.
