Absolutely not. That is not what experience has shown. It is not the right to strike that is being challenged, but rather the right to hire replacement workers. I can give you some examples, such as what happened with the Quebec Government. When it called for central services to be defined, it asked for 110% of the staff to be involved to meet essential services and therefore required to work. It simply showed that there were too few workers in the health sector.
Take the example of the health system, where people are very vulnerable. It was easy to find workers to meet essential needs in Quebec hospitals without creating any kind of a disaster.
