I'm a public school teacher, and am going to file a grievance about my school admin to the school district. I called HR how to do this and was e-mailed a form that I was to "fill out". But what I received was a note stating, "Such procedure shall provide for Board review of any grievance that cannot be resolved at the administrative level. In such instances, the affected individual may request that the Governing Board review the situation. Such request shall be in writing and shall contain the basis for the appeal, including the act or acts out of which the grievance arose, identification of the Board policies and/or administrative regulations involved, and the remedy sought."
This doesn't really explain how to file a grievance. Is this a letter with documentation stapled to it that I hand someone? Is this something I need to stand in front of the board and state in person?
I assume there's some kind of format that's wanted but have no idea how it should be packaged.

Anyone who has filed a grievance against a school admin, what was your experience?
