"The email instructs us that while the kids aren’t coming in for school for three days because of the bad weather and unsafe road conditions as teachers we’re still expected to go to school!!"

Apparently you should blame your principal for this. My mother is a teacher at a public school in Sofia and they are not required to go to school for these three day when the students will be off as well.

You could be grading papers, preparing lessons, etc. at home during these three days just as well.
