I know many students (grad-sometimes undergrads) that had there name taken off publications last minute just for submission. And, this is at one of the most liberal wel know universities in Canada. No action possible. Also, I know many students that performed work for 2-4 years, and the supervisor kept saying it's not good enough. Red flag is when your program is 3 year PhD, or 1 year master, but most people leave around 6-7 years, and 2-4 years respectively. Where is that problem? Ask the average time people take to do their PhD's. If they can't get you finished, while you enter with straight A's top 10% of your class. What is going on here?
