I'm currently a full-time student working nearly full-time at Steve and Barry's as a "head cashier" (let the Employee of the Month jokes fly!) at our Grand Rapids location. My responsibilities are indeed varied, and kinda change day-to-day depending on who is at the store. Technically speaking, I'm 6th in line in terms of authority at our store, behind our three managers and two key holders (assistant managers). My basic duties are too keep the cashiers and floor associates in line, fix any problems that arise at the front desk, and occasionally manage my own "B-team" to get a particular project completed.
Nine times out of then I manage to stay off a register as I normally am better suited to getting things done on the floor of the store. Generally I'm in charge of the two tee-shirt walls, our Starbury section, and our Men's denim section. For the most part that is done because thats what I've been working with for over two years, and I'm one of the only people who know how to do almost everything "right" in most sections (esp those listed above).
Sure, working in retail sucks, but I've had more than enough fun there. I've been looking to get a new job (maybe), as an opportunity has arisen to sell Volkswagens, Volvos, and Mercedes' for a living. I'm not sure if I want to do it, given the unpredictability of the car market at the moment, however I'm still looking into it, and would gladly work there if they needed help.
