Review the "headnote" $($summary of the case decision$)$ in the SCC decision in Communications, Energy and Paperworkers Union of Canada, Local $30$ v$.$ Irving Pulp & Paper, Ltd$.,2013$ SCC $34.$ You will note that the decision was not unanimous. The majority decided that:

Select one:

a$.$ the random testing policy was justified because of the evidence of an existing problem with alcohol use in the workplace.

b$.$ arbitral jurisprudence recognizes ah unqualified right of employers to unilaterally impose workplace rules on their employees outside of the collective bargaining process.

c$.$ the employer exceeded the scope of its rights under the collective agreement by imposing random testing without first demonstrating that there was a problem with workplace alcohol use.

d$.$ the appeal should be dismissed. The board departed from an arbitral consensus that has attempted to strike a balance between competing interests in privacy and safety in the workplace. In doing so$,$ its decision was unreasonable.
