My co-authors want to remove my name from manuscript because I am "not in science anymore," how to correct this? Two years back, was working as an research associate then have to leave the lab due to some family issues. My work was significant enough to be included in the manuscript and I was told that my experimental results will be a part of the manuscript and I will be coauthor in the paper. 

Time has passed, the paper was rejected, revised and submitted. Now, the paper is again in communication, and I am being told, that as I am not in science anymore, my name is being dropped from the paper. I am trying to contact them but they are not responding. I am very much in science, but have taken a break. What should I do, if my name is removed from the paper?
Authorship wars are common and they suck. I suggest you discuss your plans to reach out to the journal editor with the primary PI, maybe they can change their mind. I don't know what being in science or not has anything to do with your contribution being ignored but I would understand an argument that suggests a ton of work has been done since you left to bring the paper to publication.
