Um, it's NONE of your business why she's missing so much. I would imagine if her missing so many days were a problem, the school would handle it. Most teachers don't get paid for taking too many days off. When they run out of PTO, just like the rest of us, they no longer get paid when they miss. And you were WAY out of line to get her home number from someone in her family in order to HARASS her at home. Which is EXACTLY what you did. That is harassment and completely out of line.
