One of my agents, Agent E, had forewarned us casuals that summer will be a slow season for casual work.
This is attested to the reasons that there will be less staff who will ill or possibly apply for leave during this time. Another for the current situation is the financial recession.
I know this for sure as Agent E had always texted me to inform of work for weeks before hand. However, I hadn't received much in the last two weeks. So I guess I should watch my spending in the next three months (although I'm not doing a very good job at that!)
