Advice needed on this situation. I've always been able to wfh on a flexible basis. After a period of serious illness & being in hospital I've been wfh more often, usually about 3 days per week. This was agreed with my manger. We have a monthly one to one meeting & now my manager has said the wfh agreement needs to be more structured ie. set days. This is difficult for me due to my illness. Some days I'm fine & other days not but there's no real pattern. Not sure if I should ask for a meeting with HR or how to proceed. Any advice appreciated.
