my dad owns a print shop and i can write story after story of really ****ing dumb **** things that employees do. had 1 guy stack 2 yes 2 full boards of wet ink right on top of eachother. runed $2000 worth of paper then *****ed that he wasn't getting payed enough to work for a small shop. thats 1 story i have countless others but i would be here all day long typing. the long and the short is this: People will do dumb thing if they dont learn then you fire them. i wouldn't give most 2 weeks before i fired them.
