In 1899, Johnson became co-owner of the business with Henry B. Endicott, which was renamed the Endicott-Johnson Co. Under his presidency, the company grew to eight factories in Broome County, New York, employing about 10,000. Endicott-Johnson was the first company in the shoe industry to introduce the 8-hour workday, 40-hour workweek, and comprehensive medical care. This 40-hour work week was a unit-production based wage rather than an hourly based wage. Despite paying some of the highest wages in the industry, Endicott-Johnson was consistently profitable.
