Killing the Job is usually heard in a union shop environment when a worker is working way too fast. Working way too fast or even slightly faster than the minimum speed you can get away with takes work or paid for time away from other union members.
Union Worker 1: Holy fuck Man! You better tell Weed to slow the fuck down! Union Worker 2: You got that shit right, he's fucking killing the job!
