Lost sheet with parents numbers?

[worried23xxx]

I wrote a note to myself on paper with 2 parents numbers on so I could ring them after school.

Its not in my planner or the classrooms I have checked. No clue what I’ve done with it but obviously worried and not sure what to do?

Report it to your gdpr person. Was it just the numbers or the names too?

Pass it on but it's probably nothing to worry about.
