I currently wfh 1 day out of 4 day week. My elderly parents health has been bad for a few years now. They are carers for my sibling with learning difficulties. I put in a request to wfh an extra 0.5 days in the week so wfh 1.5/4 to allow my sibling to come to mine while I work. Respite for them if you like. It was refused but instead I could swap my wfh day to this other day requested. If I want to have additional 0.5 wfh needs to be formal request bearing in mind discussions are in place to consider taking it away altogether for admin later in the year. Currently another colleague same role is allowed to wfh 1.5/3.5. Is this reasonable?
