Their conclusion is based on a study revealing that ten of their previous clients who use photo identification badges have had no incidents of employee theft over the past six-year period. The directors recommendation is problematic in several respects. In the first place, the directors argument is based on the assumption that the reason for the Jack of employee theft in the ten companies was the fact that their employees wear photo identification badges. However, the evidence revealed in their research establishes only a positive correlation between the lack of theft and the requirement to wear badges; it does not establish a causal connection between them. Other factors, such as the use of surveillance cameras or spot checks of employees briefcases and purses could be responsible for lack of employee theft within the ten companies analyzed. In the second place, the directors assume that employee theft is a problem that is common among their clients and about which their clients are equally concerned. However, for some of their clients this might not be a problem at all. Forexample, companies that sell services are much less likely to be concerned about employee theft than those who sell products. Moreover, those that sell small products would be more concerned about theft than those that sell large products. Consequently, even if wearing badges reduces employee theft, it might not be necessary for all of the firms clients to follow this practice. |
