Worker Right to Know Act

Worker Right to Know Act - Amends the National Labor Relations Act (NLRA) to limit the scope of allowable union security agreements to requiring employee payment of union dues or fees related only to collective bargaining, contract administration, or grievance adjustment necessary to performing the duties of exclusive representation.

Requires, under NLRA, employee consent in an annual signed written agreement before a union may accept that employee's payment of dues or fees for purposes beyond the scope of the union security agreement as limited by this Act. Requires such an agreement to include a ratio of the dues or fees related to the limited purposes and those related to other purposes.

Amends the Labor Management Relations Act, 1947 to prohibit payroll deduction for union dues unrelated to the limited scope purposes, unless a written agreement authorizes such deduction.

Requires, under NLRA, employers to post notice of worker rights to organize and collectively bargain, as well as of the limited scope of any union security agreement. Directs the National Labor Relations Board to prescribe the size and form of such notice.

Provides, under NLRA, that employees subject to union security agreements who pay dues and fees for the required limited purposes shall have the same right as any union member to participate in union affairs related to such purposes (collective bargaining, contract administration, or grievance adjustment).

Amends the Labor-Management Reporting and Disclosure Act of 1959 to require every labor union to attribute and report expenses by function classification in detail necessary to allow its members to determine whether such expenses were related to collective bargaining, contract administration, or grievance adjustment necessary to performing the duties of exclusive representation or were related to other purposes. Requires disclosure under such Act to employees required to pay any union dues or fees (under a union security agreement) as well as to union members. Directs the Secretary of Labor to prescribe related regulations.
