The Mahoning County Board of Developmental Disabilities (MCBDD), an employer, and MCBDD employees held a collective bargaining agreement that contained a grievance arbitration procedure. In 2007, the employee union filed a notice to begin negotiations for a new contract. When MCBDD later held a board meeting, the union members were found to be picketing outside the building where the meeting was being held, holding signs that related to the contract negotiations. MCBDD filed an unfair labor practice charge alleging that the union violated the 10-day notice requirement for picketing. The State Employee Relations Board found probable cause that the union did commit an unfair labor practice charge. The union appealed this decision, asserting that the notice requirement is a "restraint of its right to picket and is therefore unconstitutional." How do you think the court of appeals ruled? Why?
