A holiday celebrated in the USA on Election Tuesday each year. It commemorates all the hard working engineers that wear
polo shirts on a daily basis, but are still asked from time to time by their tie-wearing bosses to put on a tie in order to meet with a customer. It is customary for engineers to wear a polo-style shirt, buttoned all the way up, and an accompanying neck tie on this
day. It has widespread observation in the states of
Michigan and Virginia.
