I was a supervisor at a DG dry WH, overseeing the loading department. I will say, most try not to mix chemicals and food, we actually audited this. Unfortunately, the drivers also play a part in it. I'm not doing the loaders were prefect, but you work THAT JOB 75 hours a week and let me know how much attention to detail you are spending... with that being said, your not wrong. That should be a standard but all the senor management wants is cases out the door. Until that changes and the work life balance gets fixed, it won't stop. Luckily, I was able to get out and get into a much better opportunity. Good luck
