New job
We had a new computer operator start in the data center. First day, first hour, he hits the exit button near the door to leave the computer room. Only it's not an exit button like it was at his last job. No, it's the emergency power off button.
An investigation was launched, his former employer was contacted, and sure enough there was a button near to door that you had to hit to exit at his old job. Next day a clear plastic cover was added over the EPO button. Oh, the new operator did get to keep his new job.
