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.
When employment starts, so does the employer-employee relationship. This type of relationship is defined by the kind of contract the employee has in the company. It revolves around the things they talk about and disclose to each other before the start of the employment. And before such employment, it is necessary that the company has certain basic information about the employee. This is basically for accountability purposes and for the sake of having a complete and uniform record of all employees.
