During an organizing drive, unions have a variety of tools/actions at their disposal to exert pressure on the contractor to voluntarily recognize the union (or at least not interfere with the organizing process.)

Identify ONE of these options that you think would be a good strategy for a construction union to pursue.

Explain why you think this tactic would be effective.

Explain the circumstances under which the union could/would engage in such activity as well as any caveats or limitations to such action.
