Boomerang employees made up 35% of all new hires in March 2025, the highest share ADP has tracked since 2018. That changes the question from "should we ever rehire a former team member" to "when does it make sense, and how do we do it without losing the team that stayed." This guide walks through both.
ADP Research found that 35% of new hires in March 2025 were people who had previously worked for the same employer, up from 31% a year earlier. In the information sector, nearly two-thirds of new hires were returning employees, roughly double the prior year.
For mid-market employers, the talent pool you already trained is now a meaningful part of your hiring pipeline. The question is no longer whether boomerang employees belong in your recruiting plan. It is which ones to bring back, on what terms, and how to set them up to stay.
Why boomerang employees are now part of mid-market hiring
The volume of returning hires has grown alongside two pressures most CHROs are now navigating directly. Voluntary quits have fallen more than 25% from their March 2022 peak, shrinking the pool of candidates actively on the move. At the same time, the post-AI-layoff correction has put a wave of recently departed staff back on the market.
Careerminds surveyed 600 HR leaders who had run AI-driven layoffs in the prior 12 months, and more than a third had already rehired for more than half the roles they cut. Over half of those rehires happened within six months. The result is a sizeable pool of recently departed talent who already know your systems, your clients, and your culture.
A study published in the Journal of Management compared boomerang managers to internal and external hires and found their post-rehire performance matched their pre-departure performance, with no statistically significant drop. Boomerangs come in productive and stay productive.

Why former team members come back
Returning to a previous employer is rarely a default choice. It is usually the result of three forces operating together.
Better compensation and seniority on return
Boomerang hires are not coming back where they left off. Visier found that returning employees earn around 25% more than they did before they left, well above the average raise for staff who stayed put. They use the time away to build leverage, then come back at a more senior level.
A clearer view of the alternatives
Many leavers discover that the next employer was not the upgrade they expected. ADP Research attributes part of the 2024-2025 boomerang surge to economic uncertainty and lower geographic mobility, both of which narrow the field of credible alternatives and make a former employer look more attractive.
Personal networks and alumni channels
Word of mouth still drives recruiting at the senior level. Former colleagues hear about open roles before the broader market does, and a quick call from an old manager often arrives before a job ad goes live. The alumni relationships you maintain now determine which boomerangs you can attract later.
When rehiring a former team member is the right call
Not every former employee belongs back on your payroll. Three conditions, taken together, are the strongest signal that a rehire will work.
They left voluntarily and on good terms
The boomerang research base is built almost entirely on voluntary leavers. Arnold and colleagues, in the Journal of Management, studied 1,318 boomerang managers and found that their performance after rehire was not statistically different from their performance before they left. That holds for voluntary leavers. Involuntary exits are a different category and warrant different judgment. Start the rehire conversation with people whose original exit interview was constructive and whose offboarding was clean.
The original reason they left has been resolved
A returning hire who walks back into the same problem will leave again. If the trigger for the original exit was a manager, a comp band, a missing growth path, or a culture issue, you need a clear answer to "what is different now." That answer should be specific and verifiable, not a hopeful framing. If you cannot point to the change, the rehire is a bet against your own data.
They return inside the institutional-knowledge window
The longer a former team member has been gone, the less of their original advantage is left. Inside the first year or so, most of what they knew about your systems, clients, and team is still current. Past two years, the systems, the team, and often the role itself have changed enough that the institutional memory premium has largely evaporated. Inside the window, treat them as a returning insider. Outside it, assess and onboard them as a strong external hire.
When rehiring a former team member is the wrong call
Three patterns reliably produce a second exit, and each is visible before the offer goes out.
The underlying issue is still there
If a former team member left over a manager who is still in seat, a comp structure that has not been revisited, or a workload that has only grown, you are recreating the conditions that drove them out the first time. Rehiring without changing the conditions is the most common reason boomerangs jump again.
Existing team relationships are unresolved
A returning hire walks back into the same team. If they had open conflict with current colleagues or a leader, those relationships do not reset on day one. Brief the team, get honest feedback before the offer, and only proceed if the people who would work with the rehire support the decision.
The role or company has changed past recognition
A boomerang's value comes from what they already know. If the function has been restructured, the tech stack has been replaced, or the strategy has shifted, the institutional memory premium evaporates. At that point, you are paying a familiarity premium for someone who has to learn the job from scratch.
Action item: Build a short "rehire eligibility" rubric for your hiring managers. Three boxes to tick: voluntary exit, root cause resolved, return inside the first two years. If any box is unchecked, escalate the decision.
How to make boomerang employees part of your talent pipeline
Once the decision is made, execution determines whether the rehire performs or becomes an expensive second exit.
1. Build the alumni relationship before they leave
Treat every voluntary departure as a potential boomerang. Run a clean offboarding, log the exit interview honestly, and stay in light contact through a simple alumni channel. The cheapest boomerang is one who reaches out to you first.
2. Run a structured interview
A returning candidate still gets a full interview. Use the conversation to test what has changed for them and what they expect to find changed at your end. Pull the original exit interview into the loop and walk through it together. Build the conversation around interview questions that test how their thinking has changed since they left.
3. Negotiate terms in the open
Salary, title, seniority, and tenure recognition all need to be settled before the offer is signed. A returning hire often expects credit for prior service. Decide your policy in advance and apply it consistently across all rehires.
4. Reboard, do not assume
The biggest mistake employers make with boomerangs is skipping onboarding. Systems change, policies change, and the team is rarely the one they left. AIHR recommends a reboarding plan that adapts your existing onboarding to cover what has actually changed since they left.
5. Brief the existing team before day one
The team that stayed needs context on why this person is coming back, what their role is, and what it means for them. Done well, a returning hire signals that this is a place worth returning to. Done poorly, it reads as favoritism.
6. Schedule structured check-ins through the first year
Boomerangs are most at risk of a second exit during their first year back, when the gap between expectation and reality is widest. Treat that year as a full onboarding period. Build monthly one-to-ones into the first quarter, then quarterly through month twelve, with a structured stay conversation around month nine.

FAQ
What is a boomerang employee?
A boomerang employee is a former team member who returns to work for the same employer after a period away. The gap can range from a few months to several years, and the return can be in the same role, a more senior role, or a different function entirely.
Are boomerang employees worth rehiring?
Often, yes. Research in the Journal of Management shows boomerang managers perform on return at the same level they did before leaving, and they typically reach full productivity faster than external hires. The decision still hinges on why they left and whether that reason has been resolved.
How long after leaving will a former employee come back?
Most boomerang returns happen within the first year or so of departure, while the former team member's institutional knowledge is still current. Returns become much less common past 18 to 24 months. Beyond that point, treat the candidate as a near-new hire for assessment and onboarding purposes.
Do boomerang employees expect higher pay than when they left?
Usually, yes. Visier found that returning employees earn around 25% more than they did before leaving, reflecting the experience and external offers they have collected during their time away.
How do you onboard a returning employee?
Build a tailored reboarding plan that covers what has actually changed since they left, including systems, policies, team composition, and strategy. Skip the generic new-hire orientation, but do not assume they remember everything. Treat the first 12 months as a real onboarding period.
What is the biggest risk with rehiring a former team member?
Recreating the conditions that drove them out. If the manager, the comp band, the workload, or the culture issue that triggered the original exit is unchanged, the rehire is likely to leave again, often around the one-year mark.
