Rather, it was very basic stuff, like being told to come in at 5:30AM to feed a cell line only to have the PI show up at 2PM, throw the experiment in the garbage, threaten the student's livelihood, and then demand they stay until 11:30PM redoing the experiment. Over and over again, at random intervals.
I asked around about this stuff because a family member now works in the field and had some startling experiences, only to find that this is apparently almost universal, and that what I'm describing is on the lighter end of it. There are stories about labs at elite universities where the grad students have set up secluded spaces to go hide from their PIs and cry. It's everything you've heard about working as a developer at a video game company, dialed up to 11.
