Final answer:
Labor unions representing entertainment industry workers, including those associated with SAG-AFTRA, historically ended a 118-day strike that was part of the broader labor movement for improved wages and working conditions.
Step-by-step explanation:
The group of entertainment industry workers who ended their 118-day strike were members of various labor unions representing skilled laborers, as well as actors governed by institutions like the Screen Actors Guild-Association of Radio and Television Artists (SAG-AFTRA). In the historical context of labor strikes, the workers typically sought better wages, shorter hours, and improved working conditions - all central to the collective bargaining process. The strike, a form of labor activism, demonstrates the continuous tension between management and laborers throughout various periods, including the significant entertainment sector in places like Los Angeles, where disruptions could have vast economic impacts on productions and the livelihoods of those involved in the industry.
