Manager threaten to slap me

Arianna

Me and my shit Manager don’t get along because of the fact she’s never doing her job and always outside smoking cigs or marijuana and even has stolen money from our job. Today we got into a disagreement about this and she was threatened to get me fired and got on the phone with my store telling her she was going to slap me. My store manager said I needed to leave. I’m 16 and she’s nearly 50. I’m tired of this and I’m wondering what I should do?
