As of June 30, 2020, approximately 46% of our employees were represented by the Communication Workers of America ("CWA") or the International Brotherhood of Electrical Workers ("IBEW"). During the third quarter of 2019, we reached new agreements with each of the CWA and IBEW, which represented all of the above noted represented employees. Therefore, there are no collective bargaining agreements that are scheduled to expire over the next 12 months. We believe relations with our employees continue to be generally good.
