If there has been no prior requirement to sign an annex for a salary increase in favor of the employee, should we now assume that, due to the 3-day deadline for submitting an electronic employment record to the NRA, we will be required to sign annexes for all salary increases?

The legal basis for submitting an electronic employment record for a change in base salary is either a signed additional agreement (annex) or an employer’s order in the case of a unilateral salary increase.

The date of signature of the respective document must be declared in the electronic record, and from this date the statutory 3-day deadline for submission begins.

Therefore, there must be a signed document reflecting the change—whether in the form of an annex or an official order.
