Fonzie becomes involved with other issues. Highlighting actor Henry Winkler's off-camera work, several episodes dealt with civil rights of people with disabilities. Concerned that students with epilepsy were denied their chance to attend public school and play sports, he intervenes to resolve the issue; he also learns sign language to communicate with a woman working at the municipal power company. And he pushes Chachi to continue working with his disability when Chachi himself just wants to quit because things will be hard. Such advocacy builds on the previous season's episode where Fonzie hired wheelchair-using Don King to work in his garage, promising to provide workplace accommodation for his employee.
