I almost got injured at work today. It involves a ladder and heavy boxes

Some idiot put away the truck wrong and placed these heavy as hell boxes of frozen nuggets up high where it didn't belong. I tried to get it down with the step ladder but two boxes were on top of each other and i needed one only. Im trying to push the second box back up but the first falls almost knocking me backwards off the ladder and i managed to get it to fall to the floor. The second box slams into my chest i felt myself slip so i had to grip the shelf for support while shoving the box back up. Could have been real bad had i actually fallen
