Hey Wayne,
First of all, I'm no longer a CAFETY representative, still a member, but I have no official position within the organization.
As to your point about Ms. Speiss and holding ASPEN accountable. This is an unusually black and white situation. She's on the record attacking alumni. If she is in fact currently on the ASPEN payroll as an alumni outreach person, you bring this to everyone along the chain of command, so there can be no buck passing.
It's also an active case of abuse, and may be an opening to get the local Protection and Advocacy organization involved. If nothing else they should be able to point you in the right direction as far as how to make a complaint against an employee of a facility that services individuals with disabilities.

While yes you can hold Aspen liable if they hired Amber and were unaware of her internet activities, they're even more liable if they were aware of Amber's activities, and even more liable if they were supportive of Amber's activities.
If of course she's doing this not as an Aspen employee, there is no liability in this case for Aspen.
