Recently implemented “shift-work equations” based on studies of the human sleep cycle have reduced sickness, sleeping on the job, and fatigue among shift workers while raising production efficiency in various industries.

我想问的事为什么粗体字部分不用and fatigue anong shift workers and have raised,第二个

and连接的have raised与have reduced 并列？

谢谢解答！

我想着这里是reduce sickness, sleeping and fatigue的并列吧。你认为呢？

好像不是吧

这样的话sleeping前就要加and

og解释了前半部分，没有解释后半部分

个人觉得从语法上可以这么用，但是句子表达的重心会有些区别。
