When World War II ended a decade after the passage of the LNRA, unions tried to level the playing field for wage cuts due to the wage break during the war, which led to a strike. Many people saw these strikes as economically destructive, and union practices such as store contracts were becoming less and less popular. Critics of the closed store said it allowed unions to monopolize employment by limiting membership or closing it down altogether. They also argued that the closed store would allow unions to compel reluctant people to provide financial assistance. By the 1930s, the closed store had become a generally negotiated agreement for the protection of labor organizations. These and other methods have been known as “union security.” Less extreme than the closed store is the union shop where the employer can hire a worker who is not unionized if the new employee joins the union within a specified time frame. The membership maintenance agreements stipulate that all workers in a company who are members of a union at any given time and who do not renounce their affiliation within a “flight period” must remain members of the union for the duration of the agreement; Otherwise, they will be laid off from their jobs. An agency shop is even more open than the union shop: although employees are obliged to pay sums equal to union dues, they are not obliged to join the union. In the United States, there are many detailed variations of these union agreements. A two-thirds majority of union members in place to support the store agreement is required. The status of closed businesses varies from province to province within Canada.
The Supreme Court held that the second part of the Charter of Rights and Freedoms guarantees both the freedom of associates and the freedom not to participate, but workers in a workplace largely dominated by a union have benefited from union policy and should therefore pay trade union rights, regardless of affiliation status. However, the objectors of the war had the opportunity to pay the sum to a registered charity.
