Dollar Tree review: ruining store

Have worked in company for 4 yts... Newanager comes in, I was in charge of front end... Now iys a total mess nothing done right.. Also left me in store with no manager 3 times.. The others got transfers so I can't... Real sad cause i'm a hard worker, never late, never calls out very. Loyal employee no. I need to quit. Sad real sad... Many customers complain daily...
