How to place an order on the combination of the posts
First of all, you, as the leader of the organization must notify the employee of the imposition of duties. For this purpose issue a notification. The employee after reading have to put your signature, that would imply its consent to the combination.
Since the second employment contract would be inappropriate, make an additional agreement. Be sure to specify in it the size of bonuses to base pay and the term of this agreement. The wording of the conditions may be as follows: "For work on the post (specify) executed this supplementary agreement, the employer agrees to pay to base pay of 10000 (ten thousand) rubles per month. The agreement shall enter into force from the moment of its signing by both parties and is valid for six months."
In addition to the agreement, employee must sign and local acts. For example, if it is assigned the liability, make an agreement about full individual material responsibility (towards the cashier). Also you can familiarize the employee with additional duties under the painting.
Make order on combining positions. Here be sure to include the title and name of employee. Specify that combination of positions is done without increasing the length of the working day. Enter the amount of the surcharge to the basic earnings – this can be a fixed rate, maybe a percentage of basic salary. In the basis, specify the number and date of this supplementary agreement.
Sign the form and give it for examination to the employee. If he wishes to copy, duplicate administrative document. Reassure him with a blue seal of the organization.
