The main case in which it is necessary to renew the contract is the expiration of the labor contract concluded previously. For example, if the contract was concluded for a period of 3 months, after this time it must be re-signed. When this is made official dismissal and the hiring of a new Treaty with adding records in the work book. A new contract can be concluded for a fixed term or permanently.
If the organization changed Director, place of work, legal address, the contract with employees pereselyaetsya only with the consent of employees. If you change some conditions of operation just executed an additional agreement to the previous agreement, a work book is not getting any records. If over time you have accumulated a large number of additional agreements, the employer still has the right to renew the contract without the permission of the workers.
If your firm has changed its name and type, for example, of the closed joint-stock companies became open, the workbook is entered for a record, and with employees pereselyaetsya the contract. This is done usually at the General meeting, which discussed the new working conditions. Thus workers should not lose the privileges offered by the experience in previous organizations. If the employer violates your rights, you can go to court.
In any case, changes in the employment contract or the renegotiation are made only with the consent of the employer and the employee. You should inform about all changes in the contract, and you should carefully read all additional agreements, and re-decorated the treaties. If you do not agree with any condition, do not sign any documents, otherwise then you will not be able to prove his innocence in court.
