Recognition of my work, at least earlier in my graduate program, was actually one of the few things I've been happy with -- good supervisors will be very clear in crediting their students for implementing projects (early in the students' grad careers) and figuring out how to extend projects and drive them forward (later in the students' grad careers). For instance, when giving conference talks, my PI and others will put a small photo of the student when presenting slides corresponding to the student's work.

Working with early-stage PhD students and helping supervise them has convinced me that the job supervisors have is legitimately hard. Sure, the supervisor wouldn't have anything to show for their efforts without students to do the grunt work, but understanding what the frontier of research is, and figuring out how to push that frontier in achievable ways that are relevant to the rest of the community, is extremely difficult. Most supervisors I know work insane hours to keep their labs running.

My issues arise with the personal mistreatment I've received from my supervisor -- none of what makes his job hard requires making abusive comments directly to me or other profs about my personality and work, nor does it require refusing to work with me for >12 months on the paper describing a project so we can get the work published.
