In the school system, if a child has an IEP, the child’s parents can call an IEP meeting at any time for any reason. That means teachers, therapists, and an administrator step away from their work with other students, substitutes need to be hired, etc. No one tells parents that they must really limit their meeting requests to when it’s dubbed “really important” or some such thing. If they want to meet 12 times a year or more, they have the right to.
My point is that this is how we choose to address issues of disability in this country. A person with a disability is not asked to stand back, wring their hands, and wonder if they are taking up someone’s precious time when advocating for their needs. Advocacy is generally very much encouraged in our culture. Grumbled about, maybe, but generally enshrined as protected and necessary.
If a person is reporting a violation in bad faith or due to a personal dispute that has nothing to do with disability, not ok. If it’s a genuine concern, they have the right to make that complaint.
