I’ll only add coworkers when they are former coworkers. I’m typically in management roles or some sort of leader capacity. It can get really sticky when you can see why someone was really out that day, late, etc.

I’m wondering if there had been any study on this before. I’ve worked with a wide array and I don’t think it’s limited to millennials. I think this is how it’s always been in business. The higher-ups swear like sailors behind closed doors and get angry at those lower on the food-chain if they so much as say ‘Damn’.
