Final answer:
The right of workers to join trade unions and engage in collective bargaining in Canada is established under the Canadian Charter of Rights and Freedoms. Forming unions in Canada requires a sufficient number of workers to express their intent, and is facilitated by laws that restrict how much employers can lobby against these efforts.
Step-by-step explanation:
The right of workers to join trade unions and engage in collective bargaining is established under option A) the Canadian Charter of Rights and Freedoms. This is part of the fundamental rights in Canada that allow workers to form and be part of labor unions. These rights are protected and the processes for forming a union are made considerably easier in comparison to other countries like the United States. In the U.S., the National Labor Relations Act of 1935 grants similar rights, demonstrating that workers are legally entitled to organize and engage in collective bargaining with their employers. This includes the right to strike, as long as it is within the bounds of the law.
In Canada, the process to form a union does not require a separate election date; instead, a union is officially recognized when a sufficient proportion of workers express their intent to unionize. This is unlike in the U.S., where an election is held and both supporters and management can lobby for their respective positions. Moreover, Canadian law restricts management from excessively lobbying against union formation.
