Final answer:
The correct answer is B: The union has little to offer except promises while the employer's promises carry significantly more weight with the employees, which is why unions are not held to the same standard as employers during a representation election.
Step-by-step explanation:
In a representation election, a union is not held to the same standard as an employer in making promises. This is because the union has significantly less to offer compared to the employer, and its promises are more speculative in nature. Indeed, while the union can pledge to work towards certain benefits or conditions, it cannot guarantee them as an employer might when making promises. Answer B is therefore the most accurate: The union has little to offer except promises while the employer's promises carry significantly more weight with the employees. Furthermore, the National Labor Relations Act supports workers in forming a union, and the National Labor Relations Board (NLRB) serves to mediate disputes between unions and employers, ensuring fair practices during a representation election.
