Yeah, I might have another one:
Being accused of being unreliable and uninvested.
Company had a project deal with a v important university, and had to participate once a week for a term to ensure that the research supported our project. I went along to the uni every week, without fail. Spent more time than agreed and supported PhD students with all means possible (financial, equipment, mentoring etc). Gave links and contacts for future jobs and shit (had a wine already), and we had to give a talk to an auditorium of students at the end of the semester about the project progress. During my talk I received a text, so I left straight after i gave my presentation. Winter, dark. Public transport.
Next term when I return to give the PhD students an update on the process, to a small research group of less than 10 PhD students and 2 professors. One little shit professor stands up and talks about my leaving early in the December of the previous year, that I missed some very important PhD students' work and it would have been crucial to my project, XYZ. And that I am sooooo unreliable, that there is no hope. He embarrasses me unnecessarily in front of a wide range of students and says that i am not committed to this uni- company project, and it's because of people like me that so few students take engineering XYZ. You could have heard a pin drop in that room.
Why did i have to leave early and unexpectedly? My house was being broken into, and I was sent a text by my little sis who had driven there to drop something off. She saw & heard people in the house in the darkness and knew that neither me nor my DH would have been at home at that time.
Did I ever say to the professor? No. Does it still hurt? Hell yes
