In my experience Boomers, Gen X and older Millennials generally want to socialize at work. They grew up in a office environment where you were constantly around your coworkers and social media was in its infancy.
Younger Millennials and GenZ mostly want to make a paycheck and go home. They generally don’t want to socialize with people outside of their circle. I sometimes think genZ is way happier at home 24/7 and don’t want human interaction. Could also be they just don’t have the money for it.
