A union representative has come to your office and asked you to recognize her union. You tell the representative that you need to think about it and ask her to return in one week. In the meantime, you send out a form to each worker asking them to indicate whether or not they want to join the union and tell them to drop the closed form, without their name on it, in a collection box. Have you committed an unfair labor practice? A) Yes, because you did not explain why you were asking for the information. B) No, because you need this information to deal with the union's request for recognition. C) Yes, because you can never ask workers about their interest in joining a union. D) No, because the workers don't sign the form.
