Let me rephrase, the work load probably added to the stress of him finally snapping. You are right, that no one else snapped under the current work load, but many of them complained about it. They also could see his stressing out due to the fast pace of technology changing for the machines (keeping up reading manuals). So it was no surprise when Uyesugi snapped and shot up the place.
For Xerox to contract out the delivery happened shortly after that event. So someone in charge was looking for ways to reduce work load/stress factors on the techs. Also I know a guy who used to deliver recently and he was told it's to reduce stress on the techs. He was told that they don't want another Uyesugi happening.
He accused other techs of sabotaging his machines, letting him get blamed for incompetence.
He said he was being watched by law enforcement.
He became withdrawn and stopped interacting socially with his coworkers.
I don't care what the tech was told. It's still an attempt to explain individual mental illness and the resulting violence using external factors that do not have that impact on "normal' people.
Unless, of course, Xerox exclusively hires people with a documented history of mental illness. Then, their precautionary reduction in stress might be prudent.
As for the overload of technical training, the company was going to train him on the new machines. They can't continue to sell and service outdated machines when better ones are available. That's nuts!!
According to testimony from Uyesugi's father, Hiroyuki, Uyesugi was normal until he started working for Xerox in 1984.
In 1988, Byran started to complain that he had a poking sensation in his head.[5][6][7]
After being transferred to another workgroup, Uyesugi began making unfounded accusations of harassment and product
tampering against fellow repairmen. They had difficulty dealing with him. Former co-workers who knew him reported the
other members of his team allegedly ostracized him, making him feel isolated and withdrawn. Uyesugi reportedly made
threats against other co-workers' lives. In 1993, he was ordered to undergo psychiatric evaluation and anger management
courses after he kicked in and damaged an elevator door. Uyesugi was arrested for third-degree criminal property damage.[4]
Co-workers told Dr. Michael Welner, chairman of the Forensic Panel and the forensic psychiatrist who interviewed Uyesugi
prior to trial, that as early as 1995, Uyesugi was openly talking of carrying out a mass shooting at the workplace were he to
be fired.[4] He complained that his co-workers were engaged in patterns of harassment, back-stabbing behavior, and spreading
of rumors.[8]
In the period leading up to the shootings, Xerox management had become increasingly committed to phasing out the type of
photocopier that Uyesugi serviced. He resisted learning the replacement machine, fearing that he could not keep up with its
technical demands. After working around his refusal to train on the new machine, Uyesugi's manager insisted on November 1, 1999
that he would begin training the next day. In his interview with Dr. Michael Welner, who examined Uyesugi when the defendant
brought an insanity defense, Uyesugi said he had believed that if he refused to take the training, management would fire him.
He told Dr. Welner, "I decided to give them a reason to fire me."[8]
https://en.wikipedia.org/wiki/Xerox_murdersMaybe red flag laws would have stopped him. Oh, wait. The people who heard him make threats didn't report him before the laws. Why would they do that under a red flag law instead?
Makes no sense. Anyone concerned enough to take a threat seriously is going to report it, red flag law or not.
