Death of a pet - sick leave

I have made the difficult decision to help my pet cross the rainbow bridge. I’m planning on taking a few sick days (day of the injection and 1 or 2 days after) for my mental health and to grieve since I know I wont be able to function at work.

I’m 99% sure sick leave is the way to go but just in case I missed something, I’m asking you folks.

I’m under the PA collective agreement.
