This isn’t the first time that the satanic number has caused Slonopas trouble at work.

During his first day on the job in April 2011, Slonopas was supposed to be assigned the number 668 to use when he clocked in. But the human resources department gave him the wrong number — 666 — instead.

Slonopas, who said he became a born-again Christian about 10 years ago, complained and was given a new number.

In July 2011, the company changed time clock systems, and once again Slonopas got 666. This time he quit. The company apologized and he returned to work a few days later.
