It doesn’t happen often, but I really get irritated when one person makes mistakes on something that was a group effort. For example, if a co-worker were to miss an important deadline on a team project. It’s unfair to the people in the group who made their deadlines. Because I know I get irritated when co-workers miss deadlines, I try to always make sure goals are clearly communicated to everyone on the team. If it happens anyway, I try to find out what I can do differently so the problem doesn’t repeat itself
