This area of law is mostly confined to employees who are covered by a collective bargaining agreement, which is most often achieved through a duly authorized labor union. Individuals and their union might have claims that fall within the jurisdiction of the National Labor Relations Board.
National Labor Relations Act.
The National Labor Relations Act protects members of collective bargaining units – unionized workers from action taken an employer to interfere with organizing efforts or with protected concerted activity, in other words, joint or group activity by non-management employees.
The National Labor Relations Board adjudicates disputes brought to it be employers and, usually, employees. Employees whose employer interferes with organizing, even for workplaces that are not yet represented by a union, or with joint or group activity can file a complaint with the NLRB, which will declare the rights of the parties involved.
Union Activity – Retaliation.
Many states, including Kansas, have laws that make it illegal for an employer to retaliate against an employee for engaging in union or union organizing activity.
