During a campaign to organize a union at Total Manufacturing Co., two employees of Total asked other employees in the break room at Total if they would sign cards indicating their support of the union. The Vice President for Human Resources for Total was in the break room at the time and overheard the conversation about signing cards to support the union. That Vice President said to the employees who had been asked to sign the cards supporting the union that they should know the facts before they signed the cards, that in signing the cards, if the union won the election, they were giving up their right to decide later if they wanted to join the union and that they would be required to pay union dues if the union won the election. The Vice President also told the employees that they would be obligated to be union members and pay union dues even if the union was not able to improve their pay or benefits through negotiations with Total.
Were the Vice President's statements an unlawful interference with the union organizing process? If so, what law applies?
