It is as it says. I've just found out that the ideas that my supervisors have been picking holes in and discouraging me from using, saying they aren't feasible, need more work, aren't unique, don't fit within my work, they've given to my colleague (who has the exact same supervisory team). I have never talked to my colleague about my work, my research questions, my survey questions but lo and behold he has the EXACT SAME survey and research questions as I do. The only difference to our work is a model. I may even be researching in the same area as my colleague due to some issues with my study site. All of the discouragement by my supervisors has caused me to work at a slower speed trying to find new ideas which I actually witnessed one of my supervisors feed to my colleague today in a group meeting where my colleague presented their work! Where in my case my ideas are flawed for me, they're apparently not just good for him to use but he's getting great feedback. I'm getting negative feedback and concerns over time being taken over my work. It looks like I'm being used like a data or ideas mine for everyone else. This happened before with a colleague and I stopped talking to them about my work. My supervisor has told me that I'm stupid, lack the ability to process higher order thinking, however, on the other hand is quite happy to take my work and use it for his prodigy. I've already had issues with one of my supervisors in the past and it was escalated to a higher level where I made my point. I don't know what to do this time as this is plagiarism on my colleague's part (they've admitted they knew they're doing the same work as me - they're also a year behind me) facilitated by my supervisors. HELP!
