Employees shall have the right to organize and bargain collectively through representatives of their own choosing. The majority of any craft or class of employees shall have the right to determine who shall be the representative of the craft or class for the purposes of this chapter. No carrier, its officers, or agents shall deny or in any way question the right of its employees to join, organize, or assist in organizing the labor organization of their choice, and it shall be unlawful for any carrier to interfere in any way with the organization of its employees, or to use the funds of the carrier in maintaining or assisting or contributing to any labor organization, labor representative, or other agency of collective bargaining, or in performing any work therefor, or to influence or coerce employees in an effort to induce them to join or remain or not to join or remain members of any labor organization, or to deduct from the wages of employees any dues, fees, assessments, or other contributions payable to labor organizations, or to collect or to assist in the collection of any such dues, fees, assessments, or other contributions: Provided, That nothing in this chapter shall be construed to prohibit a carrier from permitting an employee, individually, or local representatives of employees from conferring with management during working hours without loss of time, or to prohibit a carrier from furnishing free transportation to its employees while engaged in the business of a labor organization.

No carrier, its officers, or agents shall require any person seeking employment to sign any contract or agreement promising to join or not to join a labor organization; and if any such contract has been enforced prior to the effective date of this chapter, then such carrier shall notify the employees by an appropriate order that such contract has been discarded and is no longer binding on them in any way.
