With all due respect, on the notice paragraph, it specifically says that the business, not the individual, must provide notice. In this context, a business is determining the use of language—which happens, but you guys are encoding this in law—to which its employees will be subject.
That's why it's problematic. You have your justice minister making challenges about the notwithstanding clause and its use and in respect to language protection, but then you're allowing a business owner to make a charter decision for his or her employees.
