The disease associated with "passing the buck" which, in the workplace, is normally associated with passing off a task or responsibility to someone else, either in your own working department or in another department altogether.
Passthebuckitis is extremely contagious, especially if a deadline has passed or if the task involves something that you aren't familiar with doing.
After forgetting to prepare a presentation for the upcoming meeting, Melissa told the organizer that it was actually Jessica who was responsible for presenting, thus, 'passing the buck'. Jessica, then fearing for her job and reputation, told the meeting organizer that she had thought it was Mark who was to prepare the presentation.
Melissa has done this on several occasions and suffers from passthebuckitis. Jessica caught passthebuckitis when trying to defer responsibility to another coworker.
