I am a person who does not have an "invisible personality". I talk, help around and friendly with everyone. It took me a great deal of efforts to be finally able to open up, which let me make many connections at workplace and otherwise. This attitude helps me learn from their experiences too. Recently, I was slut shamed in my absence, in front of everyone (in a meeting) for being able to talk and hangout with the guys (majority of lab mates were guys). I was even accused of many things and the professor insulted me which stripped me of my dignity (again, in a meeting with the entire lab). I believe everything was blown out of proportion based on some baseless rumors. The PI even commented about my personal life. I could not stand being insulted and left the lab.
I would be soon starting my PhD and I do not want to face a similar situation again. What are the Do's and Don'ts that I should be taking into consideration while entering into a purely professional environment for smooth sailing of 4yrs of PhD? What if my superior at the new workplace is equally toxic? Is work environment at research labs generally so toxic? Since many people normalized this behavior?
