Not so casual
Pinnacle advertise as "casual - choose your hours through our app".
In Canberra, what this actually means is that they assume you have full time availability.
The Pinnacle office will ignore the unavailabilities you put on the app, and call you up for shifts during times you have already said you cannot work. If you don't accept shifts because you are unavailable, the office will treat you rudely, and then stop offering you shifts on days that you are available. There are very few weekend shifts offered.
When you do accept a shift, the start and end times are frequently changed without your consent (in my experience, moving the shift outside my available hours), and you have to call the office and get the times changed back to the shift you agreed to. Shifts can also be cancelled without explanation (even as close as 3 hours prior to your shift starting).
In Parliament House, you will not be trained. Stressed supervisors do not have time for you, and instead get angry at new staff for not knowing what to do. They frequently expect you to stay back late, with shifts that are supposed to finish at 10pm or 12pm regularly extending until 2-4am.
The pay is good, but for me, honestly not worth it.
Mostly late weeknight work, Shifts can be changed & cancelled, Office ignore your unavailabilities and are rude when you do not accept shifts that you cannot do, Poor workplace culture.
