This has always been the key, but I suspect too many employees lacked the power to say it. Some of my best friends are people I met at work. I met my wife at work. Clearly, I am not against interacting with coworkers. I am, however, against anything that forces me to interact in a certain way with a group of people I didn’t choose to interact with.
That is just time spent doing a thing that isn’t important to me after we have spent the last couple of years learning how important it is to dedicate time to the important things.
Figure out what is important to your people and they will participate. Waste their time with frivolous nonsense, and they won’t. It’s really that simple.
