About a year ago, a colleague became suddenly ill, with a very scary life threatening condition.
She was off work for a long time but has recently returned. She is a shadow of her former self and is struggling with even the most basic aspects of her job. Everyone has tried to absorb many of her responsibilities to help out, but she heads an entire department so there are many things she cannot hand over. Consequently she is making some rather big mistakes.
Everyone feels very sorry for her and are being as sensitive to the situation as possible, but her presence is starting to be more of a hindrance than a help.
Is it unreasonable for me to think that she returned to work too early, and that she should take some more time off to fully recover? How would you even go about bringing up the subject to her line manager?
