As of September 30, 2022, approximately 42% of our employees were represented by the Communication Workers of America ("CWA") or the International Brotherhood of Electrical Workers ("IBEW"). Approximately 1% of our represented employees are subject to collective bargaining agreements that are scheduled to expire within the 12 month period ending September 30, 2023. We believe relations with our employees continue to be generally good.
