A lot of backstory but I will try to be brief. I am employee of USA university but work abroad at a research nonprofit serving industry. (industry meaning an industry in general; many companies) My assigned handlers at the research nonprofit have power to ban me from the research non-profit facility, which would lead to unemployment and loss of residency. Access to the research nonprofit facility is a type of funding because academics don't normally get to work on tools this expensive. The (non-scientist) handlers don't help train me on equipment, get access to the research nonprofit facility and its resources, don't plan experiments, don't collect or analyze data, etc. When I was starting out and asked the handlers for help they indicated I was external and any issues I had with access or training were my own problem, and that asking the handlers for help was inconveniencing the handlers from their own work activities.
Generally the handlers are mean to me and take away opportunities to present my data to the industry sponsors which are afforded to my peers at research nonprofit who are internal. The handlers invoke the contract which gives the handlers all discretion in this area. My USA bosses threaten me with the handlers banning me from the research nonprofit facility if I do not make slides about my data and let the handlers present it. When the handlers present my data in situations where they don't think I will be able to see, the handlers just put their own name next to it, not mine or any of the USA people/institutions. My friendly colleagues at research nonprofit who do see such presentations then show me what the handlers are doing. I kept my head down and worked independently of them for a year and a half to get data in this tough situation. Now that my contract is up and the handlers and USA bosses can't hold employment/residency as leverage anymore I would like to publish my data ethically and independent of the handlers that do not satisfy any criteria for authorship I am aware of.
Including the handlers as coauthors would also be against the Publication Policy for the research nonprofit and EU university that handles my Visa. However USA universities I am aware of do not have a written Publication Policy and research nonprofit would likely defer to the USA universities in a formal dispute. USA bosses say I need to put handlers as coauthors because not doing so would threaten the project. Since the handlers presented the slides I authored to industry USA bosses say that counts as coauthorship of any publication resulting from my time here. Also the handlers are managers of some of my peers who did contribute to my work. What I see as threats of being banned from the facility if I do not list them as coauthors USA bosses say is actually a type of direct support of me that I should be rewarding them with coauthorship.
Sorry, I feel that was already too long. Any advice on how to handle this? Just don't write the paper? Create a messy dispute? Acquiesce? I already have 30 or so papers, so while I would like to show productivity from this stint it won't make or break my next career move.
