Since it is required to be precise and ask one question at a time, I had to split my problem into two. The first part (background) is mentioned here:
Gifting co-authorship if the topic of research was suggested by my boss?
The second part is here. So, I had finished 40% of a paper 1 as a postdoc in institute X. And, I had resigned from X on 31st of May. After completing the paper 1, I am planning to work and write paper 2 which will be an extension; probably a much advanced version of paper 1. I will start working on paper 2 from July/August and probably submit it in November if everything goes according to the plan. But for paper 2, I need experimental data and even though I had many options for sources to get the data, I thought it was better to seek permission from my boss at X before I use their data.
Also, note that the topic of research for paper 1 was was suggested by my former boss at X, please see the link I mentioned above.
But my boss at X has two conditions: First, I am required to have affiliation of his research unit for paper 2. Second, in the acknowledgement section, I will have to strictly mention that the research of paper 2 was funded by a project grant from his research unit.
In reality, he had the data from the year 2008, from a private seismic survey company XYZ and such data is very regular thing to obtain in any seismic survey. I have such data as well from my previous job profile as a geophysicist. I can easily get more of such data and permission to use them from other companies without any hassle.
As a result of this conflict my relationship with him has also got strained. I tried to clear things with him through a meeting, sent him two emails, but he did not replied. He has probably burnt the bridges and avoids confrontation. He may also be upset from me as I am going away from his clutches. He had even restricted me that I cannot contact the company XYZ directly for asking them for the permission to use the data.
Is this not a form of bullying?
Also he made it sound as if I was stealing their data, on the contrary, I was merely seeking permission to use them. I was kind of miffed with that, not acceptable to me.
I was thinking, that if I am allowed to use the data, I will acknowledge the company, my boss at X and his research unit. Also I would acknowledge him for suggesting me the topic of research for paper 1. Regarding the data permission, I have done this before as well in a different institute with another professor. It was never a problem. A simple acknowledgment sentence in the paper has been sufficient for such purposes.
So how fair are the demands of my boss at X?
