A friend's boyfriend is a postdoc, and has just been told this by his supervisor. He's in a STEM subject (trying not to be too outing, but it's more T/E than 'pure' science) and does mainly computational modelling.
His supervisor has told two different collaborators to remove him from the author list and use different (and apparently inferior) models instead. The models had already been finished and sent, so it wasn't like he said he'd do them then hadn't.
Friend is very upset - the boyfriend is a visiting researcher in another country/different time zone etc at the moment so away from her as well as his home institution and supervisor. She said he was almost crying when he spoke to her.
She's asked me whether it's normal or whether I knew what he should do (she isn't in academia, I'm a PhD student so although know a bit about it this is beyond me!).
I know I only have one side of the story, but surely that isn't normal?! I thought your supervisor would be pleased if you were doing well!
I presume the only thing to suggest is to speak to somebody higher up? Or do postdocs have a pastoral person? One thing I can't understand is why the collaborators have agreed to remove him - surely that should be their/their bosses decision?
