I really loved this class and think it was excellent since you actually learn a practical skill (how to negotiate)! It is very different from a traditional course (there is almost no lecturing, most of the class is spent partaking in mock negotiations with peers and then debriefing from them)! The course has an extremely light workload--there is only two papers that you have to write. There are no exams and only 20ish pages of reading a week (you should do the reading because it helps with the papers).
The other major piece of the class was participation. It was worth 40% of your grade. This is obviously really scary looking at it. However, it is a bit less daunting than you might think. You can earn participation in a few ways: contributing to class discussions and submitting notes that you took on the class.
I understand that I participate on average more than most people, but it doesn't mean you shouldn't take this class if you don't. The negotiation exercises were really fun (they are almost entirely 1:1, so you aren't speaking in front of a group) and the class simply wasn't much work.
Also, discussions were very short most of them 30ish minutes (despite it being listed as being 3 hours long).
I would 100% take this class again over any of the other engineering ethics courses especially given what I've heard from the others. It's fun, easy, and you learn something practical.
