Being promoted to a position that sucks worse than your current position. Your new title may include such misleading terms as "senior" or "manager" but in fact mean more hours for less pay and a false sense of moving forward in the company.
low guy on totem pole: Hey Stu, congrats on your promotion demotion last week!
Stu: (eyes red, hair greasy, piles of papers in heaps on his desk) Thanks bro, it's great finally being a Senior Manager in the office. I work 70 hours a week now but I'm making $800 more a year and I'm really valued here!
