I know things have been far from perfect lately, but that's the situation in the entire retail sector. Several of my former co-workers quit and are now regretting that decision. It was easy to find a new job, but it was impossible to find a new job that offered anything more than Macy's. Same lack of job security everywhere, same issues of being understaffed and overworked...
What they did acheive is losing their seniority and are now starting all over again, with nothing to show for it.
What I'm saying is, if you are not planning to leave retail altogether, you might as well stay where you are.
