How to resolve authorship issue of a conference paper?
You may just have to go along with all the boss types. What is fair, what is customary in field, and what is forced on you can all differ. By countering the last, you can also wind up forcing yourself out of the organization. While it is probably your best option to find a better place to work, being forced out is probably not the best option for your career. 

But if such things are customary in the field you work in, then you just go along with it as a (sad) consequence of working in that field. Many fields have non-contributors listed on many papers. I also realize, of course, that your field and their field are a bit different and may have different standards for authorship. But a boss can find ways to prevail or make your life miserable.
