I started off 19 years old as a cashierand worked my way to Assistant Manager 2 years later. I stayed with Murphy USA for 5 years. Your growth depends on if you are liked by management, not your worth.
The job can be stressful, extremely fast paced (in all roles). You need to be able to multi-task.
Cashiers on 3rd shift can expect to spend much of their time alone.
Cashiers on 2nd may spend half the shift alone.
This is a physical job, bending, pulling, lifting, squating 20+lbs of merch sometimes. You are constantly moving. Rarely is there a chance to sit down, or if you smoke, have a smoke break.
If you plan on going to Management levels, you'll need to have your personal life revolve around work. You aren't "off". You may need to handle an issue at the store at anytime.
The pay is horrible for all levels of workers (being in Management, i saw the profits my store and district were making). Very cheap when it comes to compensation.
I left to work for a competitor.
Fast paced, people interaction
