The triple peak day: Some of us just can't stop working late

The triple peak day: Some of us just can't stop working late

Do you ever find yourself logging back onto work late at night? Just for one crucial email or message that needs to get sent? If so, rest assured, you're not alone.

The Triple Peak

By counting keyboard strokes Mary Czerwinski, a research manager at Microsoft, and her team have mapped the typical work day for a group of Microsoft employees. They found that employees were most busy hammering their keyboards in late morning, before productivity slowed around lunch time, after which they would hit a second peak of productivity at around 2:30-3pm.

But the most interesting data was the rise of the triple peak group — a finding we've reproduced from Microsoft in the chart above. Czerwinski and her team found that about 30% of Microsoft employees studied were logging back in and busting out another work session late at night.

The pandemic changed work for the better in so many ways, but an increased tendency to jump on emails at 10pm isn't one of them. If you're a triple peaker let us know. If you're a triple peaker on a Friday though... we wish you well.

Note: This triple peak didn't show up on the overall dataset of all the employees, instead it was only pronounced in the subset of about ~30%.

Delta to increase bag fees by $10 on domestic flights this week, following JetBlue and United, as jet fuel surges

As the price of jet fuel surges amid the war in Iran, Delta Air Lines on Tuesday announced that it will hike its checked bag fees by $10 beginning this week.

Checking one bag on a domestic Delta flight will now cost $45, up from $35. A second bag will cost $55, up from $45, and a third will cost $200, up from $150. In a statement to Sherwood News, Delta issued the following announcement:

“For tickets purchased on or after April 8, Delta will increase fees for first and second checked bags by $10 and for a third checked bag by $50 on domestic and select short-haul international routes. These updates are part of Delta’s ongoing review of pricing across its business and reflect the impact of evolving global conditions and industry dynamics. Delta SkyMiles Medallion Members; customers traveling in First Class, Delta Premium Select and Delta One; active-duty military customers; and those with eligible co-branded Delta SkyMiles American Express Cards will continue to receive their allotment of complimentary checked bags.”

The move follows similar hikes by JetBlue and United Airlines last week. More are likely to come: when one major airline adjusts its fees, others tend to follow quickly behind. Delta last raised its bag fees in 2024, along with other major airlines.

Jet fuel prices were $4.69 a gallon on Monday, per the Argus US Jet Fuel Index. That’s up from the low $2 range for much of January.

Paramount reportedly receives $24 billion from Gulf funds to back its Warner Bros. takeover

Three Middle East sovereign wealth funds have agreed to back Paramount’s takeover of Warner Bros. Discovery to the tune of roughly $24 billion, according to Wall Street Journal reporting.

The company’s triumph over Netflix in the bidding war came thanks in part to financial backing from Oracle cofounder Larry Ellison, billionaire father of Paramount CEO David Ellison.

Saudi Arabia’s PIF, which last year led the $55 billion deal to take Electronic Arts private, will provide about $10 billion in the deal. The Qatar Investment Authority and Abu Dhabi’s L’imad Holding Co. is also involved.

According to the WSJ, the funds will not receive voting rights in the combined Paramount-Warner company. Those working on the deal don’t expect the Gulf funds’ involvement to spark any additional regulatory reviews.
