Women are less likely than men to ask for more time to complete projects with adjustable deadlines at work or school, new research finds.

Compared to men, women were more concerned that they would be burdening others by asking for an extension, and that they would be seen as incompetent, the study showed.

Prior research has shown that women feel more time stress than men do, and feeling uncomfortable about asking for more time to complete projects may be one important reason why, said Grant Donnelly, co-author of the study and assistant professor of marketing at The Ohio State University’s Fisher College of Business.

“Women understandably feel like they have too many things to do and not enough time to do them. We found that not asking for more time to complete tasks undermines women’s well-being and also their performance,” Donnelly said.

“But we also found a possible solution: Women were as likely to ask for deadline extensions as men when organizations had formal policies on making deadline extension requests.”

Donnelly conducted the research with Ashley Whillans, Jaewon Yoon and Aurora Turek of the Harvard Business School. It was published in the journal Proceedings of the National Academy of Sciences.

The research involved nine studies with more than 5,000 participants, including online panels of working adults and undergraduate students.

Donnelly said that for him, one of the most compelling of the nine studies was one conducted in his own class.

He assigned a discussion paper that was worth 20% of the grade to 103 students in an undergraduate business course. All students were given one week to submit the paper, but were told they could email Donnelly to request an extension without penalty.

Male students were more than twice as likely as female students to request an extension for the assignment (15% of female vs. 36% of male students).

Not asking for an extension could hurt students, the findings showed. A teaching assistant who rated the papers gave better scores to those who had asked for an extension. (The assistant did not know who wrote the papers and whether they asked for extensions, or the purpose of the study.)

“What we found is that when students requested an extension, they made good use of that time and performed better on the task,” he said. “Women may hurt themselves by not requesting additional time.”

Several other of the nine studies by the researchers involving working adults showed that women’s focus on other people and their needs played a big role in why they were uncomfortable asking for deadline extensions.

In these studies, participants imagined they were assigned to submit a proposal for an upcoming event that was due the next day, but needed more time. In the scenario, they could ask for an extension from their supervisor.

Participants were asked a variety of questions about how asking for an extension might affect themselves and their team, and how it might affect how they were viewed by others.

Results showed that women believed they would be seen as less competent if they asked for an extension. But that wasn’t the main reason that women were reluctant to request more time.

“It was their concern about burdening their team and manager with more work that most strongly predicted women’s discomfort with asking for more time on adjustable deadlines,” Donnelly said.

“Perceived burden and emotions like shame, embarrassment and guilt explained why women experienced more discomfort with asking for extensions than men did.”

And these feelings have real-life implications. Consistent with prior research, women in this study reported feeling more time-pressed and experienced more burnout than men.

But the good news from the findings is that organizations can level the playing field – resulting in women and men asking for more time on projects at nearly the same rate – by creating a formal way to request deadline extensions.

In one study, the researchers analyzed data from an online university that had a formal policy for extension requests – all students were entitled to four 24-hour extensions per semester, which could be requested using an online form.

In this case, women were as likely to submit at least one request during the semester studied as were men (24% of women vs. 25% of men). That finding was replicated in another of the nine studies.

Donnelly said he believes companies and other organizations should create formal avenues for requesting deadline extensions.

“It’s a structural issue. When organizations have formal policies about deadlines, it creates the opportunity for men and women to have equal experiences for requesting additional time,” he said.

“And we found evidence that allowing deadline extensions, when possible, can result in better work. That’s helpful for employers and employees.”
