Answer:
Kim is refusing to collaborate on team projects.
Step-by-step explanation:
When Kim decides to do the work on her own, without telling her coworkers and her boss, she is refusing to collaborate on team projects. This is inappropriate because she was specifically told she should write the report with two other coworkers and is not for her to decide wether to do it on her own or not. Nowadays being able to work on team projects is a key skill organizations seek on workers, specially in potential leaders. In this case, Kim will probably receive some kind of bad review from her boss.
