Final answer:
Beverage Bottling Company violated the National Labor Relations Act by refusing to bargain with the Cola Cappers Union, the employees' representative for bargaining over wages and working conditions.
Step-by-step explanation:
When the employees of Beverage Bottling Company designated the Cola Cappers Union as their bargaining representative and Beverage refused to negotiate over wages and working conditions, they violated the National Labor Relations Act (NLRA). This act, commonly referred to as the Wagner Act, reaffirmed workers' rights to organize and to collectively bargain contracts with employers. It also established the National Labor Relations Board (NLRB) to enforce its provisions, making it illegal for employers to refuse to bargain with unions that have been duly designated by their employees.
