When the "disagreement" is that your nosy Boomer Karen coworkers mis-gender you or disapprove of the way you live your life or think it's NBD that by the time you're their age we're going to be in the "find out" phase of the biggest disaster to hit Earth's biosphere in 65 million years, the problem isn't really with Gen Z.
Considering everyone who saw the headline and didn’t read the article jumped into the comments talking about Boomers being transphobic, racist, or science deniers, I actually am not surprised at all by the article (which is, of course, generalizing an entire generation and therefore erroneous, but not entirely without merit).
It’s not about the topics they’re disagreeing on, it’s about the ability to disagree congenially and effectively, which is an extremely important skill in any workplace.
You aren’t going to change any minds by saying, “You’re wrong. I’m right. I’m done talking to you about this.” You also aren’t going to have your mind changed if you’re wrong, as is very common in a workplace. My solution to a problem isn’t always the right one. Other times it is. I need to know how to disagree and have constructive discussions about topics I disagree with others on to reach the best solutions.
This is one of the reasons diversity is important to businesses. Diversity of thought and constructive disagreement leads to improvement. But if we outright reject those who do not think like we do we all stagnate in our respective bubbles.
Sure this can be applied to good faith dialogue on larger, more important topics as many here seem to be assuming, but it is essential on day-to-day smaller issues that people face in the workplace.
