Rightness and legality are intertwined in a world where laws are slower than public opinion and people can voluntarily choose to do more than only what the law allows for. But a more direct criticism of the legal aspect would be: getting a job is voluntary from a legal perspective, how does that make joining the associated union a compelled action? The union is part of the job. Besides, union security agreements already _are_ heavily regulated in the US.
