Pink Shirt Day is about working together to stop bullying by celebrating diversity and promoting kindness and inclusiveness. It’s about creating a community where all people feel safe, valued and respected, regardless of gender, identity, age, ability, religion or cultural background. O.I.S. is doing something a little different for Pink Shirt Day. Instead of Pink Shirt Day, we are having a WEAR SOMETHING PINK day: so SUBSTITUTE uniform item/s for something that is pink.
