Heat stick
A mostly worthless employee, who often spends more energy trying not to do work than would if s/he just did his/her job. Usually reserved to describe off-shift employees, as in their primary function is to keep the building warm overnight.
"I don't even know how TJ got hired, he never does more than 15 minutes of actual work. I'm glad he got assigned to nights with the rest of the heat sticks."
