Ups prides itself in taking all kinds of people from the street and turning them into robots that follow methods, keep the brisk pace, take the ass chewing put downs, demoralizing atmosphere and yet still are expected to not only get used to it but also to insulate the customers from it with a cheery attitude.
Mgmt doesn't have this added nugget (most of the time) because they don't interact with the public hundreds of times a day, thousands a week and millions throughout a career.
This
bottles up, and with a weak or weakened constitution can get uncorked in some bad ways with the wrong worker.
It's a risk at any job, but I can only speak to my time at UPS. I saw it in my small center with a few individuals I worked with, more often than I liked. People have enough to deal with just living life. Ups doesn't care about whatever you have going wrong and assumes you are fit to take a punching if they want you to have one.
Profits are good and necessary. But, the risk is there and will remain under the current culture. I doubt meaningful change will take place as the deceased will be viewed as expendable victims, not of the system that's in place, but of their own failures. The driver failed the daily "test" of fitness under stress and mgmt failed to recognize it.
Corporate will implement zero changes. Because on their minds - Orion is perfect, preload is wonderful, the calendar pictures reflect the Xanadu atmosphere (and it's real!) and all is working like a finely tuned machine.
