"As of May 31, 2019, we had approximately 76,700 employees worldwide, including retail and part-time employees. Management is committed to maintaining an environment where all NIKE employees have the opportunity to reach their full potential. None of our employees are represented by a union, except for certain employees in the APLA geography, where local law requires those employees to be represented by a trade union. Also, in some countries outside of the United States, local laws require employee representation by works councils (which may be entitled to information and consultation on certain Company decisions) or by organizations similar to a union. In certain European countries, we are required by local law to enter into and/or comply with industry-wide or national collective bargaining agreements. NIKE has never experienced a material interruption of operations due to labor disagreements."
