About a month ago, I began my second post-doctoral fellowship, however my former supervisor from my first fellowship keeps emailing me lists of tasks that he would like me to do for him, e.g. train new students on my former project, write a manuscript for remaining data.
The thing is, he was a horrible mentor and all-around terrible person, and I want nothing more to do with him.
My questions is, as his former postdoc, am I obligated to perform these tasks for him, even though I've moved on to a new position?
(I understand that writing my final manuscript will benefit me as well as him, but I am completely willing to forfeit authorship of all my remaining data so that I don't have to deal with this $%*&#$! anymore).
Any advice would be greatly appreciated!
