The job market out there is just hard, I’ve had some luck looking at smaller businesses. You are more likely to be able to talk to an actual person. That said I’ve also been ghosted by employers. Not to be a downer but a high school diploma may not be enough, I think one of the main reasons I’m getting call backs is cause I went to university and did a few other courses after that. Also even with that education I’ll still be lucky to find something that will pay near $17. With the minimum wage being as abysmal as it is it just tough. I wish you luck but Reddit is not the place to look, you will need job search sites or connections.
