Lost count of the number of PPA sessions disrupted by being called out to deal with behaviour issues in my class. I know I'm entitled to refuse and request it be escalated straight to SLT. In reality this is quite a difficult thing to do, with colleagues I work with every day requesting my help - it's normally far quicker for me to pop down and deal with it than for it to go through SLT What do you do? How do you manage it? Do you refuse?
