Consider the following true newspaper reports of dishonesty:
1. At a small manufacturer, supervisors had access to time cards and handed out W-2 forms each year. The supervisors pocketed $80,000 a year in the paychecks for phantom workers.
2. A manager at a busy branch office of a copying service had a receipt book of his own. Jobs of $200 and $300 were common. The manager stole cash by simply giving customers a receipt from his book instead of one of the company’s numbered forms.
3. A purchasing agent received tiny kickbacks on buttons, zippers, and other trims used at a successful dress company. The agent got rich, and the company was overcharged $10 million.
Specify what control or controls would have helped avoid each of the listed situations.
