Reasons for Writing a Handbook 

Perhaps the most important reason to create a handbook is to document the employer's expectations. Most employees want to be successful; they are eager to know what is expected of them and how they can improve. A good handbook will describe expected performance and how to get a promotion or raise, in addition to clarifying the employer's expectations regarding work hours, dress, and sick or vacation leaves.

The process of creating a handbook also helps employers improve their leadership, first by thinking through which policies are useful and practical in their specific operation. Then after concrete policies are established, employers can better manage employees because objectives for each position have been examined, benefits have been considered and perhaps retooled, and personnel policies are in
place before contentious issues arise.
