Raise your hand if you hated group work in school. Go on, raise it. Did the mention of a group assignment have you sliding down your chair, dreading the forced get-togethers with random classmates, the canned presentations, the uninspired project display? In most cases, these weren’t people’s best efforts -- usually, one person, unwilling to cede control, would do the bulk of the work.
If that was you, don’t worry, I’m not judging -- it was often me.
