I have been subbing for the past 2 years(one school dist), and I got a negative feed back from the dist office saying that the teacher I subbed gave a negative feedback,saying that I didnot do properly and was playing with the kids. I did sub her 2 days in a row. She called me and asked me to do work for her the next day also. She didnot send me any sub plans for the next day. she just called me and told me to continue what I was doing the previous day. I did the same and had 2-5mins left and played hang man with the kids. Now the dist says that she rejected me. How can I handle this?
