Does the insurance period include being on vacation without salary?

If an employee has been on leave without pay for a full month, the insurance period is not credited to him, including for the pension, since the insurance premiums have not been paid.

At the same time, if the employee worked part of the month, and part of the month was on leave without salary, and his actual salary is less than the minimum, the employer is obliged to pay the ESS in an amount not less than the minimum amount.
