Should internal personnel be responsible to destroy certain information?
Common sense dictates that payroll information and materials that involve labor relations or legal affairs, should not be entrusted to lower level employees for destruction. But, beyond that, competition sensitive information is best protected from them as well. It has been established, time and again, that employees are the most likely to realize the value of certain information to competitors. And, lower wage employees often have the economic incentive to capitalize on their access to it. The only acceptable alternatives are to have the materials destroyed under the supervision of upper management or by a carefully selected, high security service.
