Each of us will be able to understand how hard the work of a working person really is and what technical knowledge he must have.
General positions
The duties of a repairman are regulated by a standard job description. This document was developed in strict accordance with the Labor Code of the Russian Federation and other regulatory legal acts. These documents allow you to regulate the relationship between the employer and the employee throughout the country.
The instruction makes it possible to evaluate business qualities locksmith, to analyze the results of his work based on the results of the tasks performed. Any repairman directly reports to the head of the service (subdivision) of the enterprise. In particular, if we are talking about metallurgy, then it is appropriate to talk about the subordination of a mechanic to a shop mechanic.
Basic minimum knowledge
