Carnegie left on a trip to Scotland before the unrest peaked. In doing so, Carnegie left mediation of the dispute in the hands of his associate and partner Henry Clay Frick. Frick was well known in industrial circles for maintaining staunch anti-union sentiment. With the collective bargaining agreement between the union and company expiring at the end of June, Frick and the leaders of the local AA union entered into negotiations in February. With the steel industry doing well and prices higher, the AA asked for a wage increase; the AA represented about 800 of the 3,800 workers at the plant. Frick immediately countered with an average 22% wage decrease that would affect nearly half the union's membership and remove a number of positions from the bargaining unit.
