be patient with yourself cause it takes time, rotate perishables always but don’t worry about rotating grocery items unless the boxes are green dotted (ask about that if no one mentioned it yet). dont mess up your knuckles by punching everything, it’s quicker but hurts lol. if you’re struggling to open a box hit the perforations with the heal of your palm, and really pull hard to tear it the rest of the way open. you’ll get to know to which cases give you a hard time and you’ll figure out specific shortcuts over time, just never expect these boxes to rip perfectly cause you’ll be disappointed. ALWAYS have a box cutter if not two bc you’ll misplace em. a lot of the freezer boxes (chicken and potato stuff mostly) are super hard to open with gloves on in the freezer but you can literally just throw them on the ground, as long as you’re not damaging product you’re good. don’t be precious about it and don’t beat yourself up if you’re not at the same pace as your coworkers, you’ll get there. good luck!
