NIH reneges on recognizing union for early career researchers The biomedical research agency says trainees in its labs are not “employees”

NIH sent notice this week that it will no longer recognize a union of early career researchers on the basis that trainees aren't "employees." My latest for @science.org.

Is there such a thing as "gold standard union busting"?

NIH Says It Will No Longer Recognize the Research Fellows’ Union NIH leadership said the union “should never have been certified,” in an email to the union’s leadership.

Podcast Jay continues to attack the very people he promises to support, early career investigators. Now he wants to rip up the collective bargaining agreement with the NIH Fellows Union (illegal, BTW). Who's next, the NIH police union? The firefighters?

Screenshot of the NIH website page for the NIH fellows CBA, showing the page has been deleted. Superimposed over this is the “there is so war in ba sing se” woman

NIH HR deleted our CBA off the website. Luckily for us, even if the agency says there is no CBA in ba sing se, the union still exists.

Whatever you do, make sure you document the conversation, ideally put your response in writing, and cite the relevant portions of the faculty handbook/ policy when you do!

More evidence for my thesis that the right wing freak out we’re currently experiencing is entirely due to the widespread adoption of birth control and subsequent emancipation of women

Some feminists have long contested this view, often using political discourse rather than the scientific method. If gender is socially constructed, they argue, it is "mutable" and can be reshaped through political and social reforms. Feminists often refer to "biological determinism" in a pejorative sense, as they seek to reform society into a genderless one by eliminating what they perceive to be constructed gender traits.

Why did the editors allow him to make claims without citations? Which feminists, where, idk how they do things in geology but at least in neuroscience we cite our sources in an academic paper

Don’t worry guys I really stand by my claims

We gotta turn pepco into the people’s co, asap

I’m starting to get why a bunch of men were very very scared about MeToo going “too far”

Invalidating ID cards based on gender is literally a key plot point in The Handmaid’s Tale. This is horrifying.

I sat down with Dr. Jenna Norton, an NIH employee & my guest at the People’s State of the Union. She was put on leave by the Trump Admin after speaking truth to power.

Dr. Norton told me Trump’s actions risked creating a super-bug that would endanger us all.

This is so cool! When my rheumatoid arthritis flares my appetite is strongly reduced, contributing to fatigue and the loss of muscle mass that occurs with the disease. Very interested in finding out how all of these processes are interrelated!

STATE -* UNION MTN MOVEON MTN MEDASTOVCHNETWORK MOVEON

“When we speak up together we are powerful.”

@jenna-m-norton.bsky.social a guest of @vanhollen.senate.gov . Strong stuff.

This is why we refused to concede our Respectful Workplace article in 2022 bargaining for grads, postdocs, and project scientists. And likely why the employer fought it almost as hard as they fought wages.

Sign this petition against egregious union busting happening at St John’s. Employee working conditions are student learning conditions!

It’s really important to always have a paper revision due or some data to be analyzed, otherwise you would never be motivated to clean your entire house

I’d have to imagine habitat destruction and climate change have a greater effect on salmon pops than the salmon - eating sea lions who have always lived there?

Is sea lion massacre a winning political issue?

Donate to Alexis Goldstein for Maryland Alexis Goldstein is running for Congress in Maryland's 6th district because we deserve leaders who shows as much bravery as ordinary people are showing in defense of their neighbors.

Last week, I was fired in retaliation for confronting DOGE staff in 2025. Today, I launch my campaign for U.S. Congress in Maryland’s 6th district.

Marylanders show enormous bravery in defense of our communities. #MD06 deserves a Rep as brave as its residents.

Oh.

Vonnegut actually predicted this technological innovation in “Harrison Bergeron”

What NIH Staff Can’t Tell You—And Why That Matters The people who understand most clearly what is being lost at the NIH are also the people least able to say so.

One day I shall learn to put thoughts to paper better... but for now. elizabethginexi.substack.com/p/what-nih-s...

Hmmm universal human rights? Sounds sketchy!

Crucially, even people I personally think are stupid deserve to vote
