Despite the excellent work by scholars who invite us to consider disability, social justice, and business and professional communication pedagogy, little attention has been given to what a disability- and social-justice-centered business and professional communication course might look like in design and implementation. This case study offers an example of a simulation based within the "Harry Potter" universe that emphasizes the ways disability advocacy and civic engagement manifest themselves in foundational business writing theories and practices. This simulation enabled students to engage with social justice issues by understanding access as an essential part of business and professional communication.
