I think you're lacking historical context: Unions were the ones doing the fighting and killing. That's why we have workers rights to be eroded: people fought, killed, and died for them.
The government enshrining protections for collective bargaining was a compromise to end such violence. Today, if a workplace is violently suppressing your right to collectively negotiate your working conditions, you can sue them, as opposed to having to kick off the largest insurrection in the United States since the civil war. This is good for everybody.
Specifically, the events I was referring to were
"Throwing dynamite at the cops" - The Haymarket Massacre, where when the cops were called to break up a rally for the 8 hour workday, workers threw dynamite at them. The resulting fight and subsequent executions left 8 dead workers, and 7 dead pigs from the Chicago Police Department.
"Blowing up bridges" - International Association of Bridge and Structural Iron Workers's bombing campaign of non-union projects, which ultimately escalated to the an anti-union rag The Los Angeles Times getting bombed (21 dead propagandeers).
"Kneecapping scabs" - Not a specific event, just a thing that happened, or was threatened with happening, across the country
"Dragging the foreman out of their house and shooting them" - The Coal Wars, fought in West Virginia ultimately escalating to the famous Battle of Blair Mountain (~150 deaths between the miners, the the Baldwin-Felts Detective Agency, and a couple US army grunts)
