How to best address authorship issues with PI? I am a postdoc working with the same supervisor who supervised my PhD thesis. During my PhD time, it was tacitly assumed that my work is his work too. It went as far as me doing the entire planning and execution of a paper and writing the first draft, while he later looked over the draft and made suggestions on what to expand and what to change. None of the suggestions were fleshed out. Yet we are the only two authors on this paper and he wrote in the author contributions footnote that he and I both conceived of the study, I did the experiments, and both wrote the paper.
Since the paper used some of his data as well as experiments funded by a grant given to him, I obviously cannot publish anything on my own.
However, now, in my postdoc function at the same institution, I find myself in a situation where a PhD student and I are doing a lot of work for a paper and there are two professors involved. My advisor and another professor.
The current paper grew out of another study for which I did all the experiments and coding with a lot of input from the other professor (not my advisor), while the advisor wrote the first draft. My advisor ended up as the first author, even though only the initial idea of working on the topic was his, but he barely contributed to the design of the study, nor does he understand the statistics used or the experimental design.
In this follow-up paper it is, once more, tacitly understood that my advisor will be first author and the other professor the senior author. The work, meanwhile, is done by the PhD student and me with some input and supervision from the other professor.
Is it possible to somehow broach this inequality in my/our position without destroying one's future?
Additionally, I'm getting more and more messages that sound like I'll be part of more papers where I'm clearly the only person doing all the work. Is it normal to have the lab leader as a senior author even though he doesn't contribute any work, nor any meaningful feedback (simply because the methods are not accessible to him)?
And also I've been getting signals that sound like if I publish my own work, not using the data gathered at work, I'd still have to run it by my PI, and possibly have him as a co-author. This last part is particularly disturbing. Has anyone ever been in a similar situation? How do you discuss these things?
Your supervisor's conduct is blatantly unethical.  The current relationship is harming your career.  You need to find a new job.
