Set this sticker at the discretion of the employer, which issues the labour book to the employee. This forms of labor books and inserts without holograms are valid.
Work-book of the established sample, according to article 66 of the Labour code of the Russian Federation is the main document confirming labour activity and the seniority of the employee. Form of work books, the order of their production, management, storage, their employers are established by the Federal Executive authority authorized by the government of the Russian Federation.
In paragraph 2 of article 46 of the "Rules of conducting and storage of work record cards, manufacturing of forms of employment record and ensure that their employers" indicated that the forms work book and insert into it have an appropriate level of protection. And no mention of the fact that holographic sticker must be present in the workbook, there is no "Rules of conducting and storage of work record cards, manufacturing of forms of employment record and ensure that their employers", or in some other normative legal act.
