Mission driven, overworked - Teacher Achievement First Employee Review

Unsustainable stress/working hours. Constant staff turnover. As a new teacher it was incredibly overwhelming and they just threw me in with only one very busy person to coach me, no support from any other deans/administrators. Even now that I have my legs under me the job is incredibly exhausting and overwhelming, and it is very difficult to have any time for sleep/self. Work live balance unsustainable in the long run.
