The same question can be asked for a lot of jobs tbh. I don’t know really what would lead someone to do that, just for the simple fact that you’re damaging packages and potentially fucking over people who maybe can’t get refunded for the stuff they ordered. One guy did it 2x and kept his job. Peak season is super stressful and the days are long but it’s never that deep. I actually really enjoy the work, I’m by myself all day long and can go to bathroom or stop to grab food and eat on my own time all paid. Some days have been rough but I just can’t imagine the headspace of someone who could do something like that
