On October 16, workplaces all over the United States celebrate National Boss’s Day, a secular holiday in which employees show support and appreciation for their managers. According to ancient legends (and Wikipedia), the origins of this day date back to 1958, when a secretary named Patricia Bays Haroski registered the day with The US Chamber of Commerce. She chose October 16 since this was her father’s birthday and she was working for her father at the time in Deerfield, Illinois. Patricia wanted to celebrate the relationship between boss and employee, and the idea caught on.Four years later the day was proclaimed official by the governor of Illinois, and by 1979, Hallmark had started producing a line of greeting cards in honor of bosses everywhere.If your company encourages a traditional acknowledgement of Boss’s Day, go ahead and join in the fun.And if you’re not the type to buy into pseudo-holidays trumped up by the card industry, that’s okay too. You don’t have to be a tool of a big greeting card company to offer your boss a simple word of thanks. If, on the other hand, you don’t think your boss deserves a high five or pat on the back, that’s another issue.Before you blow off the day (and your boss’s ability) altogether, keep a few things in mind.
