Some examples of the ways in which a worker's moonlighting may harm an employer's business include:
• An employee steals plans and other intellectual property from her employer and uses them in her own business.
• An employee is tired, accident-prone, and marginally productive.
• A worker abuses sick-leave benefits in order to work more hours at a second job.
• An employee running a sales business out of her home makes free use of the employer's copier, fax, and computer.
• An employee of a computer and software sales and repair company does the same work much more cheaply out of his home, diverting clients that come to the employer's shop.
• An office employee shows confidential techniques from his first job to an employee at a second job.
• A worker refuses overtime because his second job begins 30 minutes after the end of his regular workday.
