Madam Speaker, I do not know what universe my colleague from Lac-Saint-Louis is living in. I imagine he lives in a world where everything is sunshine and roses.
In the real world, the employer has no interest in sitting down and negotiating. The employer was just handed incredible bargaining power on a silver platter. It has no interest in negotiating since there is no longer a balance of power. There will be only one mediator-arbitrator. The employer can simply ignore the mediator and the negotiations.
What will change if the employer keeps saying no to all the demands? The government will still be here to protect it and say that the parties are unable to come to an agreement. Obviously, the government will blame the employees, claiming that they are unable to compromise, when it is the employer that is acting in bad faith. There is nothing stopping the employer from continuing to act in bad faith, since the government will always be there to protect it and to trample on the workers' rights.
