Sharika works part-time as a cashier at an Ontario supermarket, where she earns $18 an hour. She works the same hours every week: four hours on Thursdays, three hours on Fridays, and five hours on Saturdays. Canada Day fell on Thursday this year, and Sharika did not work.

(b) If Sharika was sick and didn't work her normal days during the week immediately after Canada Day, would she still be entitled to public holiday pay. Why or why not?
