National Boss Day, also known as Boss's Day or Bosses Day, is observed annually on October 16 in the United States and some other countries. In 2025, National Boss Day falls on Thursday, October 16. The day is dedicated to employees showing appreciation and gratitude for their bosses' kindness, fairness, support, and leadership throughout the year. The holiday was first registered in 1958 by Patricia Bays Haroski, who worked as a secretary for her father at State Farm Insurance. She chose October 16 because it was her father's birthday. The day was officially recognized in 1962, with support from the Illinois governor. It has since become a popular occasion for employees to thank their managers with cards, small gifts, or gestures of appreciation, though celebrations are typically meant to be modest and thoughtful rather than extravagant. If October 16 falls on a weekend, the observance may be moved to the nearest weekday by some workplaces. Celebrations often include giving a card, treats, or a simple thank you to acknowledge a boss's positive influence on the team and workplace culture.
