About a week ago, I went on vacation for a week, and I did tell my manager of this two months in advance in a group chat, come the vacation ending, I text my manager “I have returned, and I'll be available to work starting Wednesday” to which I received no response. Two days ago, I went up to my workplace myself, but my manager wasn't working on that day. I told my coworker to ask her to text me, because I'd like to be scheduled, and I gave my coworker a sheet stating the times for my drivers training courses (I'm 15). It has been two days since then, and I have not received any word from my manager about being scheduled again. I really need money right now, so this isn't fair to me. I was wondering if there was anything that I can do about this? I do not know how to contact her other than by text, because that is how we have been contacting each other since I was hired in November of 2021..
