Had to work long hours.

Explanation:

During the Gilded Age, people had to work for as long as 18 hours a day and 6 days a week. And many of them would not earn much money from such an enormous and torturous work schedule. The end of the 10-- 18-hour shifts came when the socialists and communists from around the world called for a complete halt of production and trade on May 1. After these protests, it was set on an 8h workday with other benefits and the quality of life for workers improved dramatically.
