A union that had sought to organize a casino for years took its efforts to a new level when it projected a three-story image onto the wall of the casino. Concerned that the light was a safety hazard that could blind motorists, the casino called the police who told the union to shut off the light. The union then filed an unfair labor practice against the casino for calling the police. The casino was cleared of wrongdoing because it may have had a “trespass due to light project” and nuisance claim, although state law was unclear if either claim was viable.
