Researchers counted 200 extra hours a year at one firm. What each "can you just" costs, and how to hand it back.

Eventually, somebody in the group has to take the minutes. Somebody has to organize the offsite, welcome the new hire, chase down the follow-ups and remember everyone's birthday. In most workplaces, that somebody is a woman, and the role comes with no title, no raise and no entry in anyone's promotion file.

Authors of The No Club, the study's researchers, ran the numbers and reported the results. Across one professional-services firm in Jacksonville, women logged about 200 additional hours annually on tasks the authors call non-promotable, compared with their male colleagues. Women were asked to take it on about 50% more often, and they agreed more readily when the request came. Two hundred hours equals five full work weeks. It is a job nobody ever applied for.

What makes this a trait you should not blame yourself for

The effort is valuable, and the organization leans on it heavily. The trouble is that it goes unrewarded, not that it lacks value, and it lands on people by default instead of by deliberate choice. Nobody selected you. When the group looked around for the person most likely to agree, your face was the one that came to mind. The authors' experiments showed the pattern vanishes in groups made up entirely of women, which tells us the cause is shared expectations, not women's inclinations.

Here are the five tasks that show up most often, what each one costs, and the sentence that gives it back.

A. The notes

The trade-off: you cannot both transcribe a discussion and take part in it at the same time. Whoever keeps the notes observes the session instead of steering it.

A phrase worth practicing: "I've been the one taking notes for the past three meetings. Let's rotate starting today. Jonah, you're up."

B. The celebration, the offsite retreat, the goodbye card

The price: roughly twenty hours each quarter that go unrecognized in your performance review yet still cut into your evenings.

The line: "I'll handle the March event as long as someone else takes ownership of June. Who wants it?"

C. Onboarding the new person

Cost: their first month on the job, plus a reputation as the helpful one rather than the one considered for promotion.

Try this one: "I'm glad to handle their onboarding for the first week." Then who will serve as the formal buddy for the remainder of it?

D. The committee

The cost here is the culture committee, the planning committee, and the committee that reviews the other committees. Every one of them requires a weekly gathering, and not one of them has any bearing on the P&L.

The line: "Taking this on would mean giving up part of my current responsibilities. Which should go if this has become the top priority?

E. Everyone's follow-up

The result: you turn into the department's living archive. That work has real value, yet no one builds a promotion case around it.

Consider saying: "I'll list owners and deadlines in the summary." Once the summary goes out, every action item belongs to a named person.

The guideline

Calling something non-promotable is not a ban on doing it. It means do not do it by default. Share it out, put a system around it, or see to it that the effort is recorded. A rotated task becomes the team's job. Once tracked, a task is recognized as an actual contribution. A task you quietly keep carrying ends up defining how you are seen. Brace yourself for a bit of awkwardness the first time you return a task to someone else. That brief hesitation is what a default giving way sounds like.

Which one of the five falls on your plate? CURRENT: Give one task back this week and observe the outcome. Generally, no fallout follows, and that outcome is exactly what we want.
