So you oppose freedom of association?
Can the individuals decide to return to accept or reject the proposal on their own? Can they return to work on their own? Can they become non-Union and keep their jobs? Can they even get these jobs without joining this Union?
Freedom of association requires the freedom not to associate. New York is a closed shop state - a worker in a union shop needs to either join the union or pay union dues anyway without getting benefits. That is not freedom of association. I think John Stossel would call that law thuggery, too.
