I have objected to been told to do learning walks in my PPA time at my school, my HOD told me that PPA does not exist and I can be directed to do anything to do with teaching and learning in my 'PPA time'. I am really confused as far as I am aware we are entitled to our PPA time. Something strange is going on at my school since our new head joined. PPA times are not timetabled, they are left blank. The explanation was that this will enable teams to plan together in this time. My HOD has told me that I am been unreasonable refusing to do learning walks on other teachers in my PPA time and she is going to take this further. I explained that I have been told by my union that that is my time to prepare and plan for lessons. Can anyone shed some light? I really don't think I can take much more of this school and the bullys that run it.
