I'm the HOD of a small dept - none core, secondary. My colleague routinely responds to requests with 'I've got a free [says when free is] and I'll see if I can do it then.' She comes in at a leisurely pace and often leaves within 10 minutes of the kids. The thing is, we're on the same point of MPS and I'm pretty much doing lots of her job for her, e.g. apparently tidying her classroom doesn't fit into her frees so I'm doing her recycling to stop the place becoming a pit (it was dumped in my office), she hasn't sorted out any assessments or mark schemes, she hasn't set any homework using our system. In other words, she's like a warm body in the classroom, wants all resources provided, and doesn't appear to understand she's meant to be contributing anything at all (seems to believe that everything is the HOD's job and she only needs to do 32.5 hours a week). Oh, and her behaviour management is terrible.
It's her appraisal soon.
Advice?
