Answer:
It must give Keith representation equal to what a union member would receive.
Step-by-step explanation:
In the context, Keith believes that the supervisor is passing Keith unfairly and unethically in selecting the employees to earn an extra money for working overtime.
Keith is aware of this fact but he is helpless because he does not have an equal representation as he is not a union member of the electric utility.
Thus to help Keith raise the issue or file grievance, the union must provide Keith with equal representation as that of a union member have.
