When you are going to be absent you need to contact the office of Dean Chuen Chan (email@example.com). The best way to contact him is through his staff assistant Miu yee (Teresa) Chow (firstname.lastname@example.org). Teresa will then put a sign outside of your room to notify your students that class will be canceled. You can also call Teresa at 510-464-3222.
In addition to notifying the office of the dean you should also CC the English Department Chairs Eleni Gastis (email@example.com) and Chris Weidenbach (firstname.lastname@example.org).
