In IA, an employer cannot deduct from an employee's paycheck for a cash shortage from a common cash register operated by 2 or more co-workers, including an employer. However, there can be a written agreement with a manager (who must be a full-time employee) that the employee may be held responsible for a cash shortage occurring within 45 days before the most recent regular payday. An employer is allowed to have only 1 such agreement in effect per store.
