New post:

With Malice Toward All and Charity for None:
Oct. 10-11 CDC (Un)Firing Edition

The RIFs have begun (at the CDC)

joshuasweitz.bsky.social
And for the moment, ever downwards.

Equal parts malice and incompetence, but the incompetence ends up being a form of malice, so it's mostly malice.

One more note: there were many more RIFs on Friday night.

Perhaps the administration does not think of these as 'errors', and will claim that some RIFs were 'correct'.

We should assume otherwise: these RIFs are a form of political retribution that do not serve federal agency missions.

New reporting: many apparently fired at CDC in 'error'. This is a failure by design given that the admin does not care about fulfilling agency missions. This is the kind of error that should have political consequences.

Unserious people cause real-world harm.

There are reports that the *entire* office of special education at the US Dept of Education has been cut. These hardworking folks ensure kids with disabilities get equal access to a quality education.

America’s children deserve better than this.

"Roughly 70 Epidemic Intelligence Service officers — the so-called “disease detectives” who respond to outbreaks around the globe — received layoff notices"

There is no 'make healthy' objective here, but there will be costs and consequences, to readiness, safety, and lives.

FULL STORY HERE: Emails began flooding CDC inboxes late Friday night announcing dozens of layoffs. HR people brought back from furlough to oversee the RIFs. Disease detectives, entire Washington office, global health, injury prevention, MMWR staff among those hit.

The editors of the CDC’s Morbidity and Mortality Weekly Report (MMWR) were apparently fired today.

The precursor to MMWR began in 1878 to address emerging public health threats rapidly.

We are not “great” without it. We are vulnerable to threats from sporadic foodborne illness to bioterrorism.

Word is rippling out. The US is intentionally dismantling expertise that took decades to build, firing CDC staff (and beyond) late on a Friday amidst a government shutdown.

Knowing less will make us sick.

Investing less will cost us more.

Nihilism is no way to lead.

Via @statnews.com, the administration has apparently begun to fire HHS employees during a shutdown even as health care premiums are slated to double; it seems the administration cares very little about our present or future health.

Russell Vought has announced that "mass firings [RIFs] have begun."

Lawless. The RIFs in the spring were illegal, as Judge Illston outlined. Yes, the conservative SCOTUS supermajority lawlessly signed off. But the Calvinball Court is not doing law.

Congress can stop this. A thread: 1/
'RIFs have begun.' Vought announces start of mass firings during government shutdown
The White House budget office said Friday that mass firings of federal workers have started in an attempt to exert more pressure on Democratic lawmakers as the government shutdown continues.

As Vought tweets out 'The RIFs have begun', it will be crucial to speak up in support of the mission-driven folks all across this country who are being targeted precisely because they dedicated their professional careers to serving the public.
