I believe there is litigation on the workers comp issue, especially for front-line medical workers who became ill before vaccines were available.
My daughter found herself in the same situation, but the fatigue has mostly lifted, and her words come more easily now, after 20 months. Her employer accommodated her with a 4 hour per day telehealth postiton, but even that was a big stretch some days. She has progressed and will be resuming OR duties, where the pace is more manageable the urban ER.
