NASA confirmed it may have sidestepped sweeping layoffs that were expected, potentially saving hundreds of newly hired employees and career professionals.

NASA managers are seeking a “blanket waiver” to save probationary employees from layoffs, according to internal meeting notes seen by Bloomberg, as other federal agencies are forced to fire their newest hires in an effort to reduce employee headcount.

More government layoffs are expected on Tuesday, including around 10 percent at the National Oceanic and Atmospheric Administration (NOAA), which includes the National Weather Service and the National Hurricane Center. This would also amount to around 1,000 workers from the organization, which employs only about 12,000 people .
