Mmmmm i remember that when i worked on tills we signed out a float we counted it and verified by the manager than if we went on break our till was either locked or the cash draw was removed and put in a safe so we could be held responsible for our cash but if your using different tills how can they pin one person id personally speak to a union somethings not right as if you cant check your float at the beggining of your shift how do you know whats in there??
