West World Holding, Inc. owned an office building in Boise. The maintenance and cleaning employees for the building were represented by Service Employees International Union, Local 32, and the union and employer had a collective agreement governing the terms and conditions of employment for those employees. West World sold the building to Maiden LLC, a Denver-based real estate company, on August 27, 2007. Maiden announced that it would retain all maintenance and cleaning employees who had worked for West World. Local 32 then requested that Maiden bargain with the union over whether to continue to adhere to the terms of collective agreement with West World.

Maiden refused to recognize the union, and made unilateral changes to the terms and conditions of employment for the workers. The union filed an unfair labor practice charge against Maiden over its refusal to recognize the union. How should the NLRB rule—is Maiden required to recognize and bargain with the union? Is Maiden bound by the previous collective agreement? Explain your answer.
