While it was found that the employer had negotiated in good faith in Signal Industries, the Board of Directors found that the employer had breached the SEA on one point. When an employer intends to make a technological or organizational change affecting a significant number of workers, it must first inform the union at least 90 days before the change is implemented. The union then has 30 days to end the opening of collective bargaining. The employer complied with these obligations. In a newly certified bargaining unit, collective bargaining is initiated when either the union or the employer sends written notice to the other party to begin negotiations on a first collective agreement. In some cases, parties involved in negotiating their first collective agreement may face more difficulties than unions and employers with a mature bargaining history. In the signal industries sector, the employer did not fully comply with the second commitment regulation. . . .
