The article is about sciences grant, collaborations. Let us say you had a lab in Frankfurt wanting to have a 5 year collab on a subject, and they have the choice between an UK lab and a swedisch one. Which one do you think would be safe form them to take ? Excately : not the UK one. And to add , let us say you are a researcher in UK getting an EU grant. What hapenned afterward ? *maybe* the rgant runs to tis end, but afterward ? Well here you go . no more EU grant and now the Uk has to give more grants to *keep* the same funding amount of science, and the collaboration is not as easy anymore. What this has to do with worker right ? Nothing whatsoever.
Disk crisis, please clean up!
