Boss’s Day – Wikipedia

Boss’s Day is generally observed on or around October 16 in the United States. It has traditionally been a day for employees to thank their bosses for being kind and fair throughout the year, but some have opposed the concept as nothing more than a meaningless Hallmark Holiday, as well as placing unfair pressure on employees to kowtow to managers who earn more than them and exercise power over them.
