Group work = having to work in a team of more than 2 people on a project where you have to coordinate and communicate effectively with each other in order to meet a deadline.
I know that I'll be doing teamwork for many years to come and I don't mind doing it IF the other people carry their load. I only dislike teamwork when I have to carry most of the load and do other people's job. Then it's just really tiring and the empty promise people are frustrating. This has been my experience in school.
Please tell me that groupwork or teamwork gets easier and better on the job than it does while in school. Tell me that people who don't carry their load are weeded out at the job level.
