Work-from-home arrangement for civil servants with cancer

Dear PAO,

My live-in partner is a government employee. Unfortunately, she was diagnosed with cancer and will be undergoing treatment. Her sister, a private employee, said that her co-worker, who also has cancer, is allowed to have a flexible work arrangement such as a "work-from-home" setup. Is there something similar for civil servants? It will immensely help lessen the burden on my partner if she can work from home. It will save her not only a lot of time from her day-to-day commute but also the energy she needs to recuperate. Please advise.
