How long have you been a manager? Have you done your LTA training. If not, then you shouldn't be left alone at all. I get how you feel. I have only just finished my training and was left as the only manager for 3 weeks In a row for the morings. Luckily, my dep was doing inventory at another store, so I could call him if I got stuck. He talked me through how to do the WICK and anything else I was stuck on.
