When new employees resign immediately after joining, social insurance premiums are, in principle, incurred on a monthly basis. There are cases where a full month's premium is charged even if an employee works only one day, and if it cannot be fully deducted from their salary, it becomes necessary to claim it from the individual. This seminar will organize the mechanisms of the system and key practical response points.
