The same applies to the changes in sickness benefits included in this bill. It is for parents whose child has been diagnosed with cancer, for example, while they are receiving parental benefits. Before, someone could not receive sickness benefits if they had not accumulated enough hours after their parental benefits stopped. Now, they will be able to access one right after the other. That is what we mean by stacking.
