Hi,
I work in a school as a TA I have been there for 9 months now and some of the teachers and admin staff are so grumpy! I can be quite a chirpy person, but I have really turned it down because I dont want to irritate people who are already irritated. I fully understand there might be other issues as to why they are like that,but when they are like that everyday and with the children it makes me feel a bit 
Some of the kids refuse to go in the office if xxxx is there because "she will shout" , now I just spend most of my time with the students because I cant face speaking to staff who may or may not bite my head!
Any advice?
