Answer:
a. Bargain collectively with their employer through their representative.
Step-by-step explanation:
As an employee of the company and a member of the union of the company's employees, Mica has certain rights that prioritize his interests over that of the company. It also ensures that he, along with the others, have the right to oppose any mistreatment by the company.
Under federal law, Mica and his other union members have the right to bargain with their employer through their representatives. This is their right under the federal law, which not even the Natural Gas Company can ignore or declare void or baseless.
Thus, the correct answer is option a.
