So I am on permenant supply 3 days a week at a catholic school until end of year.I have not previously attended any staff meetings. SLT (RE Lead) has nobbled me to attend next week's meeting as visitor coming in to advise on RE Assessment practice. I am not catholic, have no plans to work in a catholic school long-term and am worried if I attend this one it is setting the precedent to attend every week.Needless to say I would rather chew own arm off! I did not say I would attend but what can I say to get out of it with damage limitation to my interest in CPD and kids welfare?
