Over the past few years, many large employers have tightened their in-office requirements, and plenty of smaller companies have followed. There are good reasons to want people together. New hires ramp faster when they can sit next to someone, some kinds of work really do go better in a room, and a half-empty office is expensive. This is a reasonable call for a leader to make.
What often gets missed is what the decision does to hiring. An in-office requirement changes who will apply, who will accept, and how long your open roles stay open. If you are going to require office days, it helps to go in with your eyes open and a plan for hiring around it.
What the Research Shows
The best data on this comes from large companies, so treat it as a direction rather than a forecast for a company your size. Researchers at the University of Pittsburgh, including Mark Ma, studied 54 S&P 500 companies that put return-to-office mandates in place between April 2020 and June 2023. They used more than 3 million LinkedIn profiles to track departures and more than 2 million job listings to track hiring.
After the mandates, employee departures rose about 14% compared with each company's own pre-mandate baseline. On the hiring side, the time it took to fill open roles rose about 23% on average, and hire rates fell about 17%. The people who left were more likely to be women, mid- to senior-level managers, and employees with more skills listed on their profiles. In other words, the people who are hardest to replace. Fortune and SHRM both covered the findings.
A separate study points the same way from a different angle. Nicholas Bloom of Stanford, with Ruobing Han and James Liang, ran a randomized trial with 1,612 employees at Trip.com, a large travel company. Half could work from home two days a week, and the other half came in all five. The hybrid group quit at a rate about one-third lower, with no measurable harm to their performance reviews or promotions. The paper was published in Nature in 2024.
Those were big companies in tech, finance, and travel. A 50 to 200 person company will not see the same numbers. But the direction is consistent, and it matches what many leaders see in their own pipelines: the stricter the in-office rule, the smaller the pool of people willing to take the job.
Why Senior and Specialized Roles Feel It Most
The effect is uneven. For an entry-level role in a large metro area, the candidate pool may barely change. For a senior engineer, a controller, or a head of marketing, it can change a lot.
Experienced people have the most options, and many of them have spent several years working in a way that fits around their lives. Some took jobs that let them live an hour or two from the nearest office. When your posting requires five days in a specific building, those people filter themselves out before you ever see a resume.
That fits with what the Pittsburgh study found, where the departures skewed toward senior managers and employees with more skills. The same thing happens in reverse on the hiring side. The candidates with the most options are the ones most able to say no.
Here is some example math. Say a search for a senior role would normally draw 40 qualified applicants from your metro area. If an in-office requirement takes a quarter of them out of the running, you are now choosing from 30. The hire you make might be just as good. The odds are a little worse, and the search will probably take longer, which means more weeks with the seat empty.
An in-office requirement is a hiring decision as much as a workplace decision. Make it with the candidate pool in mind.
Decide Role by Role
The simplest way to protect the pipeline is to stop treating this as one company-wide rule. Some roles genuinely need to be in the building. A lab tech, a warehouse supervisor, or a manager of a mostly on-site team has a clear reason to be there. Other roles, like a senior developer or a financial analyst, may not.
Go through your open and planned roles and sort them into three groups.
- On site. The work itself happens in the building, or the person manages people who are there every day.
- Hybrid. The role benefits from regular time together, for planning, onboarding, or team rhythm, but the day-to-day work can happen anywhere.
- Remote-eligible. The work is largely independent, and the best person for it may live outside your commute radius.
This keeps the in-office rule where it earns its keep and opens up the hardest searches to a much larger pool. It also gives you an honest answer when a candidate asks why one role is remote and another is not.
Be Specific About Which Days and Why
The word "hybrid" on its own tells a candidate almost nothing. Three days a week with the days chosen by each team is a very different job from Monday through Wednesday, fixed, for everyone. Candidates fill in the blanks with the worst version, and some walk away before asking.
Spell it out in the posting and again on the first call. How many days, which ones, whether they are fixed or flexible, and what happens during a crunch. Then say why. "The product team plans together on Tuesdays and reviews work on Thursdays" is a reason people can respect. A rule with no reason attached reads as a rule about control, and senior candidates in particular tend to read it that way.
Widen the Commute Radius
When a role needs to be in the office some of the time, the number of days changes who can take it. Someone who lives 90 minutes away will rarely accept five days a week. Two days a week is a different conversation, and one day a week or a few days a month opens the search to people who would never have applied otherwise.
Try thinking of the commute radius as something you set per role rather than something the office location sets for you. A fully on-site role draws from maybe a 30 to 45 minute commute. A two-day hybrid role can pull from a much wider circle. A role that needs people together one week a quarter can draw from anywhere, with travel budgeted in.
- Post the real schedule so candidates in the outer ring know the role is open to them.
- Budget for occasional travel on roles with a light in-office schedule, and say so in the offer.
- Ask candidates about their commute early, so neither side spends weeks on a job that will not work.
- Revisit your pay ranges and benefits for a wider geography, since expectations will vary across it.
Keep an Eye on the People You Already Have
Both studies above are as much about retention as hiring. The Pittsburgh research found departures went up after mandates, and the Trip.com trial found hybrid workers quit about a third less often. For a company your size, losing two or three senior people in a year over a schedule change is a serious hit, and every one of those departures becomes a search that now faces the same narrowed pool.
Before a policy change, talk to the managers whose teams are most likely to object, and find out who is at risk. It is far cheaper to make an exception or a role-level adjustment up front than to backfill a controller in a slow market.
Where to Start
Pull up your open and planned roles for the next two quarters. For each one, write down the honest minimum in-office schedule and the reason behind it. Where the reason is thin, loosen the requirement, and watch what happens to applications and offer acceptance over the next search or two. That gives you real data from your own pipeline instead of a guess.
If a search for a senior or specialized role has stalled under a strict in-office rule, a recruiting partner can help you work out whether the schedule or the search itself is the problem, and widen the pool either way.
