You accumulate vacation hours per 2 weeks of working. Not sure how much maybe 1-4 hours depending on shift times. It adds up after awhile
I started as a casual which means I had 0 vacation days. Instead I got a 4% on the hours I worked paid. Not until you become either part-time or full-time. For part-time you get one week and as you gain seniority it increase, for full-time you start at two weeks and as you gain seniority, it increases.
