What can we do about a model employee whose health issues have become a trial?

Q: “We have a 10-year admin employee who has incontinence issues. Other than this, she is and has been a model employee. She is 67 years old, suffers from health issues, is pre-diabetic and uses a walker. She does not have support at home to bathe regularly and she is wearing a diaper to work. We have suggested she get help through her doctor/a referral for home health care. She is not in a position to work from home—we would have to make a position in order for her to do so. This week, the employees that sit near and around her have all complained about the odor. They have added air fresheners, fans, etc. They are not saying anything or talking about her. They all feel sorry for her. The employee is immune to the odor, as having used a c-pap device, she can no longer smell. The employee is kind, gracious and in the past when this has happened, she is genuinely embarrassed. Her supervisor would like to suggest that she have her doctor refer her for disability. Every day is a struggle for her to even get to work. We are at a loss. I do not want an age discrimination claim, a harassment claim or anything of that sort. I would like some guidance on what we can possibly do for her?” - Beth, California
