It's mostly about strength in numbers. The U.S. in its history has not ever had a generation as large in population as the Baby Boomers. As a generation, they also don't tend to agree on everything.
The Millennials, another large demographic, are pegged to replace them in the workplace when the Baby Boomers actually retire. That is why the Baby Boomers are interested in courting the Millennials for work and being so "accommodating" to Millennial needs.
On the topic of working styles, keep in mind that not everyone seeks collaboration as a goal. There are those in the workplace who seek only to assert their own goals and needs. They have no intention of being collaborative. They don't want to "identify strengths from one another and make them work together."
We deny generational differences, the needs and goals of each generation, to our own peril.
