> The ADA defines a person with a disability as a person who has a physical or mental impairment that substantially limits one or more major life activity Speaking is a major life activity. Stuttering is protected under the ADA. I’ve consistently checked the box on applications and went through the interview process. YMMV, but I don’t see any issue with checking the box. It hadn’t slowed down my career/job search, and it absolutely is not unethical. Good luck to you!
