This reminds me of the show Silicon Valley, there is a subplot where one of the main characters is unassigned from his own project but not given a new team or project. Just, unassigned. He wanders around the building and eventually makes his way to the roof where he runs into a small crowd of other "unassigned" employees. They mostly badge into the office, head to the roof and sit up there all day doing nothing of importance.
when people slack at their jobs and just let other team members pick it up... it seems so scummy. Someone has to have a 'challenging' upbringing to have this be their default mode of operation.
