The term 'TYPOGRAPHER's Strike' refers to a labor dispute between the International Typographical Union and the American Newspaper Publishers Association in the late 19th century. The strike, which lasted from 1886 to 1888, was caused by the publishers' refusal to recognize the union and their attempts to reduce wages and increase working hours. The strike was eventually resolved when the union won recognition and higher wages. The crossword solution for this term is DELE, which stands for 'DELETE, ' as in deleting the old rules and regulations that were in place before the strike.
