A few years ago, the graduate students at the University of Chicago, where I teach, formed a legally recognized labor union. Last year, that union expanded to include the law school, at least to the extent that law students engage in paid work such as providing research assistance. Law students who want to work as research assistants must either join the union and pay dues, or else pay agency fees to the union even if they do not join. Either way, giving money to the union is a legally required condition of working as a research assistant.
Graduate Students United at the University of Chicago, the union, engages in political speech that some law students find quite objectionable. The union is part of the United Electrical, Radio and Mine Workers of America, which also engages in political speech. For some law students, having to give money to these causes is an unacceptable condition of employment.
Yesterday, a group of those students, Graduate Students for Academic Freedom, filed a federal lawsuit against the union arguing that the arrangement violates their First Amendment rights under cases like Janus v. AFSCME, which holds that compelled agency fees "violate[] the free speech rights of nonmembers by compelling them to subsidize private speech on matters of substantial public concern."
