Thieving employees often try to justify their actions with the case that they are not properly compensated for their skills. This is bullshit. Lots of awesome employees are underpaid and do not receive enough praise. I say "tough shit." If you were truly a great employee, you wouldn't steal.
After an offender is gone, there is still a mess of distrust and loss prevention. Everything is looked at with suspicion and once harmless actions (the 11 minute break, the digging through the stock loss garbage) bring about a dangerous kind of attention.
So don't steal. I will let you know right now that you are now that you are not smart enough to get away with it and when you DO get caught, we will all hate you for making our lives more difficult than they already are.
