Seriously, I've heard so much about how dodgy these are, about how unions state an agency cannot 'force' you to use one & REC members shouldn't be etc etc BUT every single agency is trying it!!! Why isn't there some consensus? Radio 4 were talking about it last week, with the upshot being you should demand PAYE etc but what is the teacher to do when unless you join 'we can't guarantee you work'. It's a complete racket!
