I'm not sure how much of this to share, because I don't want to reveal my identity in any way! I'll try to share only as much as I need to. A co-worker is not showing up for her assigned duties. She is at school in the building, but she simply goes about the day as she pleases. Students are suffering because of her absence. She knows exactly what she needs to be doing, but she often just shows up extremely late or not at all. I and several of my co-workers are concerned. We've started approaching this person with comments like, "We missed you today. Is everything ok?" She seems offended when we ask and does not offer an explanation. We've tried everything we can do to let this person know they are valued and missed. So....we feel we have no choice but to approach our administration about this. The last time I tried this (regarding a similar situation), I was basically told that it was my responsibility to deal with it. Now that we have a new principal, I'm hoping that things will be different. 1. How would you approach a principal about this? What words would you use to show that you're genuinely concerned, not just tattling? 2. Would you go alone or take a co-worker? 3. We just started documenting today...I wish we would have done that earlier. Should we wait until we have more documentation? Thanks!
