National Boss's Day is celebrated annually on October 16 in the United States. This day is dedicated to recognizing and appreciating the hard work and leadership of bosses and supervisors. Employees often take this opportunity to express gratitude through cards, gifts, or special gestures. The observance of National Boss's Day began in 1958, initiated by Patricia Bays Haroski, an employee at a State Farm Insurance office. She chose this date because it was her boss's birthday. Over the years, it has grown in popularity, encouraging positive relationships between employees and their employers.
