Just randomly read on facebook that the public pool where I said I would work in june opens at the end of the month this year.

I have been working there in the holiday time for some years now, so I already knew that they would just say 1-2 days in advance when I will start to work. But NOBODY told me the public pool with open a month later than usual this year. Since I said that I would only be able to work in june this year, and since it's so much later and I will probably not be able to work for just one week alone, I think they should have told me. Also since they called me and asked when I would be able to work.
