This question:
seems very related to
and
My advisor wants me to include a name of someone who has no contribution to the paper
We also have the question asked from the other side of the table
How to explain to a student that it is common to include a supervisor as a co-author
I also asked something in a more canonical sense (I think)
What are the minimum contributions required for co-authorship
but it misses the interpersonal aspects of what can happen if a junior person refuses the request/demand of a senior person. Do we want a canonical question to cover these topics that would include a list of links to authorship guidelines for different fields/journals and a summary of those statements as well as a summary of the repercussions that can arise out of saying no and a strategy for dealing with the whole situation?
