For any academics whose employer is forcing you to apply for a waiver in order to avoid face-to-face teaching this fall: consult the @AAUP Website, which has links to CDC, ADA, and EEOC guidance.

Even if you are an adjunct, if you require accommodations to do your job, your employer cannot lay you off for that. Any college that allowed online teaching in the spring mustnt say that online teaching in the fall is not possible. If they deny your request...

File an EEOC complaint, join @AAUP, and contact them for further assistance. Currently professional insurance is not available through AAUP, but academics can get insurance that covers free legal representation through many professional orgs. I have mine through @The_OAH.

Also, even if you do not feel like you medically qualify for an accommodation, I encourage you to apply for one anyhow. If enough faculty go through a formal process of applying for accommodations perhaps your institution will realize that a fully online semester is the best.

finally, talk to each other. You need not disclose the reasons for which you applied for accommodations. But you should tell each other the reasons for which you were denied accommodations. Figure out if your institution is treating full-time and part-time faculty the same.

an institution cannot discriminate between full-time and part-time employees when it comes to providing reasonable accommodations. If they hired you to do the job, and you require accommodations to do it safely, they must provide those to you.

also, I AM NOT A LAWYER. consult an attorney if you need legal advice.
but my ethical advice is this: we must help each other.
