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 downside to using an employment agreement template is the potential for building inflexibility into your business. In particular, employment law changes may invalidate or make an existing agreement out of date. If you use the same job template for hundreds of employees and the law changes, you may need to go back and have them re-sign new contracts. This would not always benefit the company, though it is a small risk to take to get the significant legal protections afforded by even the simplest of contracts.
