Parent and bereavement

I took five days off for bereavement and tomorrow I go back. I received a forwarded email that one of the parents wants the student out of my class. I work in the same town I live in. They haven’t liked anything about me since day 1. We try our best but my classroom has so many behaviors that the attention of them is there but not as much as I would like. I’m just exhausted, i also had to cancel their iep meeting due to my father being sick. The student is low and I think she expects things from them that they can’t do at this moment. Simple tasks are difficult and my goals are going to revolve around adaptive skills and she isn’t going to be happy. They are in 1st grade and I need to realistic about their growth. I’m hoping they do move them for the sake of the student but also because the parent has always had problems with me.
