Need advice from store managers.
I work in a dollarama as a part time employee while still in high school. I have worked at my location for about a year and a quarter now. For the last 7 months i have had saturdays marked off in my availibility sheet they had me fill out in september. This week i was scheduled on the saturday so i left a note for my store manager just reminding her i could not work on saturdays as i have other work. She then texted me telling me she expected me to be there or find someone else to take my shift the friday before. I told her i was not availible as i wrote on my availibilty sheet. And would not be showing up that morning. She then texted me and told me she expected a new filled out availibility by sunday with both weekend days open. Is she allowed to decide what days im availible as a part time high school employee.
( i told her it was for hockey because she kept bothering me about why i was not availible saturdays but have since planned all my activitys on saturdays)
