But does office-centric work really improve diversity? In its efforts to adapt to the post-pandemic environment, Meta Platforms, the owner of Facebook and Instagram, decided to offer permanent fully remote work options to its current employees and new job applicants. If Dimon is right, this shift should have undermined Meta’s diversity.

In fact, Meta found the opposite to be true. According to Meta chief diversity officer Maxine Williams, the candidates who accepted job offers for remote positions were “substantially more likely” to come from diverse communities: Black, Hispanic, Alaskan Native, Native American, people with disabilities, veterans, and women. Sandra Altiné, Meta’s VP of workforce diversity and inclusion, said “embracing remote work and being distributed-first has allowed Meta to become a more diverse company.”

The numbers bear out these claims. In 2019, so before the pandemic, Meta committed to a five-year goal of doubling the number of Black and Hispanic workers in the U.S. and the number of women in its global workforce. Frankly speaking, large companies usually tend to make bold promises but underperform in executing on these commitments.

However, thanks to remote work, Meta’s 2022 Diversity Report shows that it attained and even outperformed its 2019 five-year goals for diversity two years ahead of its original plans. The company substantially improved on other diversity metrics to which it didn’t commit in 2019: For instance, people with disabilities increased from 4.7% to 6.2% of Meta’s employees.

Is Meta special in some way? Not at all.

Do you think minority groups, such as African Americans, want more or less time in the office compared to white people? A Future Forum survey on this topic among knowledge workers—who can work fully remotely—found that 21% of all white knowledge workers wanted a return to full-time in-office work.

What would be your guess as to how many Black knowledge workers wanted a return to full-time in-office work? The answer: Only 3% of all Black knowledge workers would want to return to full-time work in the office. That’s a huge difference!

Another survey found that 38% of Black men and 33% of Black women wanted a fully flexible schedule, compared to 26% of white men and 25% of white women.

Plenty of other surveys show similar findings. For example, the Society for Human Resource Management last September found that half of all Black office workers wanted to work from home permanently, while only 39% of white workers did so.

What explains this enormous disparity? Well, unfortunately, Black professionals are still subject to discrimination and microaggressions in the office. They are less vulnerable to such issues when they work remotely most of the time.

In addition, Black professionals have to expend more effort to fit into the dominant cultural modality in the workplace, which is determined by traditional white culture. Code-switching—adjusting one’s style of speech, appearance, and behavior—takes energy that could be spent better doing actual productive work.

Similar findings apply to other underprivileged groups. That includes women, ethnic and racial minorities, and people with disabilities.

Since this data is widely available, why did Dimon make the dubious claim about the return to the office improving diversity? He might have fallen for the belief bias: a mental blind spot that causes us to evaluate truth claims based on how much we want to believe them rather than the data. Another problem could be confirmation bias, our mind’s tendency to reject information that goes against our beliefs.

While Dimon is absolutely wrong about diversity, that doesn’t mean remote work is a panacea for underprivileged groups. Research shows minorities deal with bullying on video calls and harassment via chat and email, as well as in other online settings. Surveys also demonstrate that men frequently interrupt or ignore women in virtual meetings, even more so than at in-person ones.

How do you address such problems? Companies need to train staff—and especially managers—to conduct remote and hybrid meetings in a way that’s sensitive to diversity concerns. This will help your team build skills in avoiding such problems and especially help minorities feel supported as you design a more collaborative atmosphere.

For example, when bullying and interruptions happen in virtual meetings, managers need to learn how to address them immediately. They can say something like, “Please let them complete their point before asking questions. Use the raised hand function so that we can come back to your suggestion afterward.”

Managers also need to check with underrepresented staff about bullying in private team member communications, making it clear that any such behavior should be brought to their attention. In both cases, the manager needs to be trained to talk to the offender, explain why it’s inappropriate, and request that they change that pattern of behavior.

Stopping online harassment of minorities is not the only challenge in remote work settings. Another is the decline of connections among workers.

For instance, research indicates that the number of connections made by new hires in the workplace decreased by 17% during the pandemic, compared to the period before the pandemic. Since the successful accomplishment of company goals often requires cross-functional collaboration, this loss of connections is worrisome. Fortunately, scholars found that connecting junior staff working remotely to senior staff during the pandemic worked very effectively to expand the network of junior staff.

Research shows that one of the primary reasons minorities fail to advance stems from the lack of connections to senior staff in the form of informal mentoring and sponsorship. To address this requires creating a formal hybrid and remote mentoring program, with a special focus on underprivileged staff.

As an example, at one of my clients, the University of Southern California’s Information Sciences Institute, we are implementing a formal mentoring program that will provide special support to minority groups. That means providing minority staff with two mentors, one from the same minority group and one representing the majority population. Doing so offers the minority mentee a diverse network of connections and experiences to draw upon from both minority and majority staff. It provides mentees with the knowledge and relationships they will need to advance, while the fact that each mentee has two mentors lightens the load on each mentor and makes the workload manageable. To help uplift the importance of the mentoring program, mentoring is included as part of the performance evaluation of each mentor.

Creating a diverse, inclusive, and equitable culture in remote and hybrid settings requires recognizing problems and taking action to remedy them. An easy way to start advocating is to conduct internal surveys to determine those issues.

The best surveys will ask minority staff about their experiences with the problems outlined above and other diversity-related challenges. They’ll also request feedback about what employees believe might be the most effective ways of solving these problems. Then they’ll integrate the best solutions into plans to address the situation.

You have probably heard the famous phrase, “What gets measured gets managed.” Once you know the nature and extent of the problems, you can work to change them systematically, rather than in one-off situations. Measure the problem, create a plan to fix it, then measure how well you are improving it.

By adopting best practices for diversity in hybrid and remote work, you’ll avoid Dimon’s failure to look at the data. Instead, like Meta, you’ll outperform your diversity goals.
