If the manager does not discuss performance problems with employees until performance-review time, employees can be shocked and defensive, and much of the potential for improving their work performance will be lost. Managers should act on problems as they occur. Manager does not delegate responsibilities to staff members. This is a common problem among inexperienced managers. By delegating certain tasks, a manager is able to keep his or her own desk clear and to give employees the opportunity to develop problem-solving skills that will improve their own career potential.
Manager takes work-related issues personally.
Naturally, a manager might be angry when an employee is late for three days in a row, or when an important task isn't completed on time. But managers must be careful not to turn work-related issues into personal ones that could spark animosity between them and the staff. Manager does not set parameters. Every management style establishes a certain set of employee expectations. So a manager needs to alert staff members if he or she wants to know the instant an inventory problem occurs in order to handle it personally.
