The National Science Foundation is reinstating probationary employees following a court ruling on the firings.

The National Science Foundation (NSF) announced Monday that it is reinstating dozens of probationary employees that the Trump administration fired last month. Why it matters: The reversal comes after a federal judge ordered the Office of Personnel Management (OPM) to rescind instructions to several federal agencies to fire probationary employees.

Following the federal court ruling, the Office of Personnel Management told agencies to begin the reinstatement of unlawfully terminated probationary employees.

The National Science Foundation is rehiring about half of the 170 people it fired two weeks as part of an effort to shrink federal agencies.
