I've just come back from leading a school trip and one of the teachers I took with me was a nightmare. He questioned every decision I made and ripped all my ideas and (extremely careful) planning apart. I think he is just someone who likes being in charge and likes to do things his own way. I like teachers to use their initiative in trips and not stand around like lemons, but surely they shouldn't be overturning the trip leader's decisions and plans without discussing it first?
Just ranting.
Anyone else had to deal with this sort of thing?
