Answer:
Such labor unions were not notably successful in organizing large numbers of workers in the late 19th century. Still, unions were able to organize a variety of strikes and other work stoppages that served to publicize their grievances about working conditions and wages.
Why? Industrial unions generally failed during the late 1800s because workers could be easily replaced since they lacked specialized skills. In contrast, employers had to negotiate with trade unions because the unions represented workers whose skills they needed.
