The public policy of the state as to employment relations in the furtherance of which sections 48-901 to 48-912 are passed is declared to be as follows:

(1) It recognizes that there are three major interests involved, namely: That of the public, the employee, and the employer. These three interests are to a considerable extent interrelated. It is the policy of the state to protect and promote each of these interests with due regard to the situation and to the rights of the others.

(2) Industrial peace, regular and adequate income for the employee, and uninterrupted production of goods and services are promotive of all of these interests. They are largely dependent upon the maintenance of fair, friendly and mutually satisfactory employment relations and the availability of suitable machinery for the peaceful adjustment of whatever controversies may arise. It is recognized that certain employers, including farmers and farmer cooperatives, in addition to their general employer problems, face special problems arising from perishable commodities and seasonal production which require adequate consideration. It is also recognized that whatever may be the rights of disputants with respect to each other in any controversy regarding employment relations, they should not be permitted, in the conduct of their controversy, to intrude directly into the primary rights of third parties to earn a livelihood, transact business and engage in the ordinary affairs of life by any lawful means and free from molestation, interference, restraint or coercion.

(3) Negotiation of terms and conditions of work should result from voluntary agreement between employer and employee. For the purpose of such negotiation an employee has the right, if he desires, to associate with others in organizing and bargaining collectively through representatives of his own choosing, without intimidation or coercion from any source.

(4) It is the policy of the state, in order to preserve and promote the interests of the public, the employee, and the employer alike, to establish standards of fair conduct in employment relations and to provide a convenient and expeditious method through the courts by which these interests may have their respective rights and obligations adjudicated. While limiting individual and group rights of aggression and defense, the state substitutes processes of justice for the more primitive methods of trial by combat.
