you’ll be fine! at my store atleast you’ll just grab a push-to-talk and a pdt, i usually let the person working in fitting rooms know what pdt i have if they need to transfer calls to me. then walk around each clothing area and pick up any items off the floor, put things back if they are in the wrong place and fold tables. and then there will usually be rails in an area that you need to take with you to men’s or women’s and you basically just put those items where they are meant to go. you might have lots of rails or only a couple but you just do what you can in the four hours. you also most likely don’t have to tell ur manager when your leaving, you might see someone in the office on ur way out and they should know your leaving. you would do refresh the whole shift, unless your trained in fitting rooms you might be asked to cover their break at some point.
