Story behind the question: I teach virtual. Completely virtual school. I had a whole bunch of students, so the school hired another teacher and we split the class. The primary tool of communication is with families is an in-house email system. I sent emails announcing the upcoming split. I sent emails introducing the new teacher. I sent emails explaining who was in which class now. The new teacher sent emails introducing herself. The new teacher sent emails verifying who was in her class. Both of us sent weekly communication. Now, to phone calls. Families have our phone numbers (not personal, just our office GotoConnect/Google Voice numbers). These numbers are given out. Calls happen. We also have synchronous online lessons that both of us invite students to via their online systems. Well, a parent sent me via text some material they weren't able to send online. Assuming she just didn't have the new teacher's number (which she ought to) or just thought our grade in general was working together, I thanked her for the materials and said I would pass them on to her teacher. Then, I receive a text from her. She has questions about some material that, unfortunately what with the student no longer being in my class, I don't have access to, so I suggest she try her teacher directly--I even provide the phone number. Well, now she's mad at everyone because no one ever communicates with her and how was she supposed to know the teachers have been changed. Sigh. So, is there anyway to guarantee a parent gets communication?
