Could be. Stopping working for the system, with massive strikes. There is nothing they fear more. But they will exercise violence first, have no doubt. They are the lords and masters of violence. With violence they have the upper hand. A difficult situation to manage.
History has shown us again and again that when capital feels threatened, it gets violent anyways. Look at how many strikes have been beaten down, shot or even bombed (look it up, the first plane-dropped bombs in the US were dropped on striking miners)
I dislike violence, and I don't think it's good strategy to start it (that's why I'm a syndicalist), but realistically, we should be ready for the reaction.
