Here is the information from the UFT Chapter Leader Update:
Know your rights about preparation periods
Among the many meaningful rights and professional protections that your contract provides is time carved out each day for teachers to do professional work. Whether you teach elementary, middle or high school, teachers are generally entitled to five periods per week (one per day) for unassigned professional work under Article 7, Sections A–C of the UFT-DOE contract (you must be logged in to view it). It is your choice how to use this time for professional duties that will best enhance your work. A teacher may decide to use preparation periods to write lesson plans; grade papers; analyze student data; research a lesson topic; meet with parents or colleagues; or do other professional responsibilities of their choice. Prep periods are self-directed; you determine what to do during your prep periods. This is a right we fought for and a right that workers without a union do not have. For information about prep period do’s and don’ts, read the Know Your Rights column on prep periods on the UFT website.
Are your self directed preps and duty free lunch respected by administration? At Middle College High School where I teach, this is not a problem.
I hope these basic rights are not being violated.
