Final answer:
Parental, paternity, and adoption leaves in Canadian jurisdictions allow up to 12 weeks of unpaid leave per year for family reasons like birth or family illness. Comparatively, Norway and Sweden have more extensive family leave policies.
Step-by-step explanation:
In each Canadian jurisdiction, there's provision for different types of family-related leave, which could include parental, paternity, and adoption leaves. The span for these leaves can vary greatly. In Canada, protection for employees includes up to 12 weeks of unpaid leave each year for family reasons, such as the birth of a child or a family illness. Maternity leave has a global presence. For example, Norway is known for offering one year of paid leave, a policy that was humorously highlighted in a viral video. Meanwhile, fatherhood is embraced in Sweden, where paternity leave involves up to 480 days of subsidized time off, which can be shared between both parents. In comparison to such policies, the rights of pregnant employees in the United States have evolved gradually over time, with the Pregnancy Discrimination Act of 1978 marking a significant milestone by ensuring the provision for unpaid leaves of absence for pregnant women.
