A template for an employee form could also contain a portion asking for the employees office extension number. This would probably be part of the form especially in big companies where an employee may be reached by another in a different branch office through phone. The social security number will be part of the template. It will provide the company everything it has to know about the employee. If he has an outstanding warrant of arrest from the police, if he is an outstanding debt, what responsibility he has, what violations he did, etc. Other possible parts of the employee form template are the date of hire of hire of the employee, whether he is on a part time schedule or a full time one, a section where he has to say whether he just graduated or not, his pay rate, etc.
Another benefit is the clear reduction in legal liability that a business can achieve by using a simple employment agreement template. When you have clear requirements for both parties written in a signed document this eliminates a lot of the ambiguity and costs associated with lawyers and courts if you are ever sued by a current or former employee (or worse yet, the employees union). As long as the agreement follows the law and the employee was competent at the time of signing, most courts will honor its terms. This can get you out of a very expensive situation!
