Illinois Law professor Matthew W. Finkin and arbitrator and mediator Barry Winograd critique President Trump’s Executive Order 14251, which excludes many federal employees from union protections and collective bargaining on the grounds of national security. The authors argue that the Administration’s justification, based on flawed data from a partisan report, misrepresents arbitration’s impact on performance management and that existing laws already safeguard national security without undermining federal labor rights.
