I don't think much of this thread is relevant. If somebody gives me a time to be somewhere, and it leads me to complex avenues of moral debate over the impact on my professional career and the opportunities in life for my children, for less than a kilosecond, then no.

Are they on time for work? Good. Are they late? Did they prevent or ameliorate that having an impact?

Will they execute what they say they will, when they say they will? We may have to wait on that.

I don't mind my employees being 10 minutes late one day and 10 minutes early the other. I understand that, with variances, you need to shoot for the mean.
