I think that's more of a fear of authority figures moreso than fear of teachers. I was afraid of certain teachers at school, the strict/authorative ones, though. Not your usual or bubbly teacher. However, I got extremely shy approaching many teachers about work.
However, I have a fear of other authority figures. I dread the thought of ever going to court for any reason, judges etc. freak me out. I also feel very weary around Police Officers, which made being jumped and detained by them a couple of weeks ago really scary, even if it was for my own good.
