Hey, I'm a cashier that got hired as seasonal and was kept. I am trained as GS and self checkout along with softlines. During my normal shift I will cashier along with covering breaks at GS SCO cashiers and my GSTLs breaks. I love doing it but I feel used sometimes. Their will often be times that I am left incharge of the front for my entire shift. Should I ask for a raise because I am doing a lot more than cashiering?
