In the practice of applying legislation on early pension provision, many difficulties arise due to the existing inconsistencies in the lists, the variety of names of professions and positions, as well as the large number of industries contained in them. Difficulties are also caused by the fact that the work on organizing preferential pension provision in some enterprises and organizations is not at a high enough level.

Unfortunately, managers and personnel workers of many enterprises still treat the maintenance of work records with annoying frivolity. With their illiteracy in filling out work books, they deprive workers of the right to early retirement and lay the foundation for a conflict to arise.

It is not uncommon for enterprises to include arbitrary names and positions in their staffing schedules that do not correspond to the nature of the work performed and the Lists of preferential professions, in accordance with which the right of the insured person to receive an early retirement pension is determined.

According to the Instructions on the procedure for maintaining work books , approved by the Decree of the Government of the Russian Federation of April 16, 2003. No. 225 “On work books”, the names of professions must be entered in them in accordance with the UTKS (Unified Tariff and Qualification Directory), and the names of positions - with the Unified Nomenclature of Employee Positions . Lists of preferential positions and professions are also compiled in strict accordance with these documents. Therefore, the basis for providing a pension benefit is work in a specific profession (position) directly provided for by Lists No. 1, 2 of industries, works, professions and positions giving the right to preferential pension provision.

Section XXXIII “General Professions” of the List dated January 26, 1991. No. 1 names electric and gas welders engaged in cutting and manual welding, on semi-automatic machines, as well as on automatic machines using fluxes containing harmful substances of at least hazard class 3.

In addition, a prerequisite for the appointment of an early retirement pension is periods of work performed continuously during a full working day.

In connection with this, when determining the right to assign an early retirement pension to insured persons who have periods of work as an electric and gas welder (gas and electric welder), I include confirmation of full employment and clarification of the type of welding performed.

When deciding on the issue of granting an early retirement pension to this category of workers, difficulties often arise in confirming the type of welding, which is associated with indicating in the work books the name of the profession - electric and gas welder without specifying the type of work performed. To assign an early pension, a clarifying certificate from the enterprise of the established form is required, confirming permanent employment as an electric and gas welder in cutting and manual welding, on semi-automatic or automatic machines. At the same time, electric and gas welders working on automatic machines are assigned a pension according to List No. 2, provided that they are constantly engaged in work using fluxes containing harmful substances of at least hazard class 3.

Employee Responsibility

The job description introduces certain responsibilities of a gas-electric welder:

• For improper and untimely performance of their functional duties within the limits provided for by Russian labor legislation.
• Violation of the regulations and rules governing the activities of the employing company.
• Offenses that were committed during the performance of labor functions. Within the limits provided for by the administrative, civil and criminal legislation of the Russian Federation.
• Causing material damage to the employing company and its employees.
• Compliance with current instructions, orders, management orders, local regulations of the organization, as well as requirements for maintaining trade secrets and other proprietary confidential information.
