Depends on your management team and district my store promotes from within and is always looking to send new associates to map (manager assessment program) Our newest area supervisor started as a cashier and with his open availability and hard work he got promoted
Without a raise.
Not very likely
You don't get a promotion
You communicate with your manager to see if there is a better position for you
I worked harder than most of the cashier for almost a year before I got a .75€ raise.
Very selective and only certain departments
Long they grade you off your speed on the register
