I used to work at Walmart. For a long time I thought better pay would make the suffering worthwhile and for a while it did. But eventually the complete breakdown of management (salaried to be exact, I was an hourly supervisor) and processes due to an over focus on Online Grocery Pickup, made me even more miserable. I left for a more fulfilling job where, for a while, I was making less money (more per hour, but less due to not working a full year).
No amount of money would ever sway me to go back to retail, but if it was just a money issue, I may not have left.
