When we see someone do a job every day, it can become easy to forget how much work goes into it. For instance, seeing delivery drivers roll through our neighborhood doesn't really give us much insight into what their company's management is demanding from them.
Although many customers would prefer to wait longer if it means their package arrives safely, these drivers are usually ordered to get to their destinations as quickly as possible. With that kind of pressure on them, some drivers may end up developing shortcuts.
However, if that shortcut involves throwing people's packages over their fences, that can lead to more destructive consequences than drivers may realize. And one sad case from California starkly demonstrates that this risks the safety of more than just the package.
