This is an official letter given by an employer in writing to the employee for the official joining of the company.
It is generally used for the communication of appointment to a new recruit at a particular organization. It lays down various information such as position offered, salary,
benefits, confidentiality policy, work policy and other relevant terms of employment.
This can generally be made binding if printed on the official letterhead of the organization and duly signed by the person authorized to hire an employee and the employee himself. The general
practice is to keep a signed copy of the same to maintain records for the organization. You may use it if you as an employer have hired a candidate for a specific role in your organization.
