First off RACE has nothing to do with it. She didn't do her job. If you think about how she went about with her grievance 
and her action( sending home a letter telling the parents she would not be returning) do you really think she could go back to Page?
 She still has her job just at a different school. Maybe she can strive and learn from her mistakes.  There where a lot of hurt feelings on both sides. So her going back is not an option, but 
bettering herself is. She will have all summer  to learn and  grow. A lot of the items listed may not be that big of a deal to you, but when it Constantly  happens it gets annoying. Having to do someone Else's work while they get paid to just sit there is not right. 
Through out this whole year she has made a lot of mistake and Burt a lot of bridges. But maybe next year at her new school she will learn to 
share the load. Page has a lot of healing that needs to happen and so does she. All this he said.... she said ... gossip needs to stop!
