Sign the Petition Save Geology at the University of Leicester

It seems the benighted halfwits running @uniofleicester.bsky.social want to gut one of the best geology departments in the country and fire some of the UK's most accomplished and important palaeontologists. Please sign the petition to save geology at Leicester. #paleontology

We need to begin to tell these stories about universities as well. So โ€”ย what did university mean to you? Contact @cdbu.bsky.social at cdbupress@gmail.com with your story. You can read some previous submissions here: cdbu.org.uk/stories/

... but they are also places that foster the messier and less quantifiable aspects of understanding ourselves, each other and the world around us. They are places whose value we only really come to understand years after we have left them.

So often universities are spoken about in instrumental language: as institutions that confer skills and training, and as engines of economic growth. Universities are both these things of course...

That's true, but the individual VC is the tip of an iceberg. More than sixty employees of my university receive higher salaries than the Prime Minister of the United Kingdom. Senior "leadership" salaries are inflated across the board, and it adds up to a really serious waste of money.
