 Not anymore. No, I guess not. I mean, if that's acceptable, what is unacceptable? 15 minutes? 20 minutes? Well, it depends. I mean, there are a lot of different places throughout the United States that are having a hard time finding good workers. So if this person's a good worker and it is 10 minutes late and you're annoyed, is it enough to fire them? Used to be. 40% of millennials said they're forgiving of colleagues running 10 minutes late. But just 26% of Gen Xers are okay with it.
