Developing a particular job description, you should consider business direction for each employee. For example, a sales manager. Prescribe that he must develop a customer base to sell, negotiate with contractors. That is, you should list all of what he should do.
In the job description and list the conditions of work, that is all, what tools he will own, and that for their work to receive. For example, these may include any professional knowledge (annual certification, training, etc.), as well as the conditions of remuneration (bonuses, allowances, etc.). The instructions specify and working time, rest time and procedure for granting leave.
In drawing up job descriptions refer to the regulations (Labour, Civil, Criminal Code). Remember that these provisions should not be piled up, otherwise they will be difficult to read. Stick to a couple of sheets of A4.
If an employee is financially responsible person, the instructions should be indicated and what will he manage. Be sure to include in the document obligations of the parties and actions in case of violations.
Instructions are issued in duplicate, each of which is signed by both parties. One copy shall be retained by the employer, the second - is transferred to the employee.
