Answer:
work rules.
Explanation:
In the United States of America, the American Federation of Labor (AFL) was established by union members as an association or umbrella body for trade unions on the 8th of December, 1886 in Columbus, Ohio. It was formed due to the dispute that arose with craft unions while they were still part of the Knights of labour.
Establishing work rules pertaining to apprenticeship standards, union member tasks, and which job duties union members would be required to do was one of the most important activities of the AFL.
