Management can also reduce the risks of employee theft by always driving around the back of the building when coming and going, checking the dumpster from time to time and walking through the warehouse at random times. Insist that your managers do the same. It takes so little time but shows employees that you are alert. It may be necessary to use undercover contract employees to detect serious thefts by your employees. They are available from a variety of sources and may disclose other problems as well.
Examples are on the job drug sales and other illegal enterprises.
Review how you handle returned goods. Many furniture retailer's procedures are inadequate. It may have been entered into inventory but was actually dropped off somewhere else on the way back. If you have the same person picking up the unit and entering it back into inventory, your risks are increased dramatically. Bottom line, hire the most honest people you can find yet maintain a healthy skepticism that they will always be honest.
