So, i have been doing some research work. i was assigned a senior staff as a senior supervisor and a more junior member of the staff as a junior supervisor.
the initial idea was mine, i collected all the data, done all the work. and the junior supervisor just revised my work to make sure i was on track.
the whole time we had a good relationship and no personal nor work problems.
then publishing time came, its a small research but an opportunity came up that it can be represented as a poster in a very esteemed congress in our field. the senior supervisor is the one who provided that opportunity in the first place.
i took permission from all included colleagues and proceeded to apply. i even said that the junior supervisor can present it and i can just tag along , she refused because she had some personal problems that will prevent her from traveling.
i wrote my self as first author, she,s a coauthor and the senior staff our supervisor
now the abstract has been accepted as a poster, and she sent me the most degrading message via mobile, saying that she can make better proposals and doesn't need me or my paper, then blocked me !!

i tried calling she didn't answer, i sent her an email saying that i am sorry if i offended her in any way and reminded her that she was the one who said she couldn't travel to present the paper

is that normal? i keep having this guilty feeling but i am sure i haven't wronged her in any way. it was my paper , my data and my work....and i even wrote her as a coauthor

It's not normal, and she's in the wrong, but next time it might a good idea to send the abstracts to all coauthors for approval before submission

I didn't understand. What is she offended about?

If she does not answer her phone or to emails then you can wait till you meet her and ask her. Hope the misunderstanding gets resolved.

Maybe the way she reacted is down to personal problems she is having as it sounds like you've done everything by the book. It's a shame about the unpleasantness but hopefully she'll see sense between now and when you next meet in person.

Certainly not normal, and probably not even normal for academia ;)
As other responses alluded to, there may be other reasons for the reason, so best not to be too confrontational IMO.

hi loomy
Congrats on your abstract-acceptance!!!
It is very good for the team! Doesn't really matter who is presenting, but it does sound like she is being petty. It is not easy to work with difficult people.

Just thread carefully, but carry on!
love satchi

maybe she expected to be the first author?

Update: my senior supervisor talked to her
she gave very weak excuses for her reaction

The senior supervisor said I shouldnt worry about her reaction because its out of jealousy more than anything else . ( which made me releived that my senior sup. didn't beleive any thing about me people might say)

As a compensation so she'll drop the subject, the senior sup. arranged for her to give a talk at a similar upcoming congress( my name was put in the talk originally but I am all for giving it to her so she can stop all this hate)

Thank u for all ur replies and thank you for hearing me out
