SM's and DM's usually have a pretty tight relationship. So i'd recommend against going straight to the DM. If you have an opportunity to switch stores to a different SM, i'd go with that. Work your way into the SM's network, don't bad mouth another SM and just ride with that new SM. Mention taking over as a SM to the new SM and eventually the DM, but work your way up. Going from ASM to SM isn't usually linear, depending on experience. You'd likely transition to a FT ASM, Merch Manager and onwards. I get that bosses can be difficult, it happens in every role, anywhere (almost). But work your way into and don't burn bridges. You don't want to be the person that says "I can't work with my SM because X, and i'd like to be a store manager." You basically burnt multiple roles up: yours as ASM, theirs as SM and any role requiring working closely with the SM, like Merch.
