Average remuneration (§ 49 ASVG), gross and subject to unemployment insurance, that the employee has received in the last four fully paid weeks or in the last fully paid month before introduction of short-time work and to which the proportionate special payments have been added. Furthermore, all bonuses that are regularly wage and salary elements must be added to the gross remuneration, according to § 49 ASVG. If no regular remuneration exists (for example, in the case of shift operations or regular bonuses for hours worked), the average of the last three months must be used. To classify part-time employees in the flat rate table, their remuneration must be converted into full-time remuneration based on the respective normal working hours defined by law or in a collective agreement. To classify employees for whom a regular allowance for the solidarity premium model or semiretirement pay is granted, the solidarity premium or wage compensation can be excluded to avoid duplicate funding. If the short-time working period is extended, the gross remuneration plus the proportional special payments must be updated according to the valid remuneration conditions. During the agreed short-time working period, all increases (for example, due to changes to a collective agreement) are not taken into account.
