This is a non-partisan event where there will be inspirational speakers showing support for teachers.
From the event information (they are encouraging painting/drawing a heart on your hand):
Join us for a peaceful and powerful gathering as we stand side by side in solidarity with our teachers, faculty, and educators. This event is open to all teachers, students, school staff, families, and supporters of public education.
We encourage attendees to wear their “Everyone is Welcome” shirts or any clothing that reflects unity and inclusion. Bring signs of encouragement if you’d like, and most importantly—bring your heart.
This is a family-friendly, peaceful event rooted in love, respect, and the belief that education matters.
