Vacation and personal hours accumulates at a higher rate. You get paid 6 holidays (without having to work) as opposed to the 2 holidays TMs over 32 average hours get.
Your also guaranteed atleast 32 hours, but will get 40 almost all the time.
The things is, I write the schedule and I work almost every weekend. It's the busiest time for us and I want to be there for my team. It's rare when I have weekends off.
