Black Monday is the name given to the mass lay-off that happened that day, at the “Youngstown Sheet and Tube Factory”. On this day, 5000 people were let go by the company. This episode shocked the whole “Steel Valley” and was the first event to a succession of companies closing or getting bought out. For Youngstown, Black Monday was tragic. Nearly half of the population went away. Black Monday was just the beginning of it, before a wave of unemployment in the whole state of Ohio.
