"Sample: 52% of the company's IMs were being sent between 6pm and midnight."

Sounded unbelievable to me! As it turns out, it's not true.

The author links to another of his articles that links to the Harvard Business Review paywalled article, but Microsoft has directly published the actual statistic behind this claim.

"Workplace Analytics data showed the share of IMs sent between 6 PM and midnight has increased by 52 percent on average."

There are a lot more IMs being sent in that time range relative to pre-pandemic, but by the given chart, it's clearly nowhere near half.

That article is irritating, it's a jumble of things in no particular order.
