If you fall ill, sickness allowance is your principal benefit. If you fall ill while receiving an earnings-related daily allowance, IAET-kassa may pay you the earnings-related allowance for the waiting period imposed by Kela. The Kela waiting period is defined as the day on which you fall ill plus the 9 following weekdays (including Saturdays). You must append a medical certificate specifying the period of illness to your earnings-related daily allowance application. You do not need to append the related Kela decisions.
