Since the “test” for implementing a policy is only applicable to unionized work environments, do you think “personal appearance” ought to be a prohibited ground in human rights legislation? Why or why not?

With the variety and extent of body piercings on many people, one would think that it is okay to have and display them in any work environment. However, this may not always be true.
A residential care facility for older people developed a new dress code policy that specifically stated that clothing needed to be able to cover any and all body piercings. The facility argued that the policy was necessary due to the number of elderly people who were uncomfortable around individuals with piercings. This new policy was grieved by its union and went to arbitration for a decision.
