The Case for Rehiring Former Employees

When an employee resigns, many employers treat the relationship as finished. Access is revoked, the desk is cleared and the person becomes a former employee in the HR system. But in a labor market where quits reached 3.4 million in September, the highest level since March 2025, many of those departing workers will be looking again within a year or two. Some of them would come back.

Why boomerangs are valuable

Returning employees, often called boomerangs, bring advantages new hires cannot match. They already know the company's systems, products, customers and culture. They have relationships with coworkers and managers. Their past performance is known, which lowers hiring risk.

They also bring something new. Time at another employer can add skills, perspective and a clearer appreciation of what the original company did well. A returning worker who says the grass was not greener can be a powerful voice for retention among current staff.

Boomerangs often settle in faster socially as well. They know who to ask for help, how decisions really get made and which unwritten rules matter, knowledge that takes new hires months to build.

Onboarding is usually faster. A boomerang may need training on changes since they left, but not on the basics. In skilled roles with long learning curves, that can save months.

The exit shapes the return

Whether former employees come back depends heavily on how they left. A respectful exit, with a genuine thank you, a smooth handoff and a final paycheck delivered correctly and on time, leaves the door open. A hostile or careless exit closes it.

Exit interviews help. They show departing employees that their views matter and give the employer useful information. Our guide to stay and exit interviews explains how to run them well.

Managers set the tone. Some react to resignations as betrayals, cutting people out of meetings or speaking negatively about them after they leave. Coworkers notice, and so do the people who left. Encouraging managers to respond graciously protects the employer's reputation and keeps future options open.

Fix the records

Many HR systems code departing employees as eligible or ineligible for rehire. Those codes are often set hastily or inconsistently. A good employee who left during a difficult period may be marked ineligible without a clear reason, and future recruiters will screen them out automatically.

Review rehire codes periodically. Make sure ineligible designations are tied to documented reasons, such as serious misconduct, and applied consistently. Inconsistent designations can also create legal risk if they correlate with protected characteristics.

Train recruiters to look past old codes when the reason is unclear. A short conversation with the former manager, where possible, often reveals that the person left on reasonable terms and would be welcomed back.

Build a simple alumni program

Alumni programs range from formal networks with newsletters and events to a simple list of former employees who agreed to hear about openings. The basic version costs little. Ask departing employees in good standing whether they would like to stay in touch, and share relevant job openings with them occasionally.

Former employees are also a source of referrals. Even those who never return may recommend friends or former colleagues. Our guide to employee referral programs explains how to structure rewards, and some employers extend referral bonuses to alumni.

Make returning easy

Streamline the process for former employees. Allow them to skip steps they already completed, such as certain assessments, when their skills are known. Consider restoring some seniority or benefits eligibility for people who return within a set period.

Stay in touch without pressure. A note on a work anniversary, an invitation to a company event or a short update on new projects keeps the relationship warm. The goal is a lasting connection, not a recruiting campaign.

Talk openly about boomerangs. Sharing stories of employees who left and came back signals that the door is open and that the company values people who grow elsewhere.

Keep the reasons in mind

If employees leave and return in large numbers, it may signal that pay or career paths are not competitive enough to keep them in the first place. Boomerang hiring works best alongside efforts to improve retention, such as clear career paths described in our report on internal mobility.

Departures are inevitable. The employers that handle them well gain more than a good reputation. They gain a pool of experienced candidates who already know what it is like to work there and chose to come back.
